Here is some more information to get you started.

• AirConnect-Synology is a package for your synology devices to automate the installation and usage ofAirConnect.
  • AirConnect-Synology releases will use the official AirConnect version + the current build date as tag/version (f.e.0.2.25.0-20200511)
  • AirConnect-Synology is compatible for almost all synology devices starting from DSM 5.0-4458 up to the newest and latest release of DSM 7
• Starting with DSM7 AirConnect, so both programs,aircast andairupnp will now run under the airconnect user (no root anymore!).And the complete package will now fully managed from DSM (Before some parts were managed in the startup scripts).

I own multiple Synology NAS devices and the current Synology Router. As long as that is the case, I will also update the releases regularly.

If a release is missing or does not work on your device, please open anissue,then I will check this and deliver it to.

Every pre-build synology package in thereleases section are including these two programs:

• airupnp
  • ForUPnP/Sonos players
• aircast
  • ForChromecast

So you only need one package to supportUPnP,Sonos andChromcast devices.

You can find the available packages underreleasesfor the following synology DSM distributions (DSM 5, 6 and 7) and the different architecture groups of the synology NAS/Router devices.

The minimum firmware version for the DSM7 packages isDSM 7.0-40000.
The minimum firmware version for the x86_64 packageAirConnect-x86_64-${VERSION} isDSM 6.0-7321.
Forall other package the minimum firmware version is DSM5.0-4458.

If thex86 (32-bit) package is not working on your device, please download thex86_64 (64-bit) package instead.

You can check which architecture you have in thePackage Arch column on the SynologyWhat kind of CPU does my Synology NAS have?site.

For all the SynologyRouters running Synology SRM you should use theARM (ARMv7 - dakota, ipq806x, northstarplus) version.If the normal ARM package is not working on your device, please tryARM Static (ARMv7 Static) instead.

On some devices, dependencies that are necessary to runairupnp oraircast are not available (mostly on older devices).These dependencies are included in the static version of the packages.This is the reason why the static packages are bigger than the normal versions.

So in general you should always use the normal package (without static in the name).Only when the normal package does not work on your device, please test the static package instead.

If the aboveARMv7 package will not work on your device, please download the latestarm-static package.The static package includes "static" binaries, that means, it includes binaries that have no external library dependencies andshould be run on your ARMv7 device if the normal ARMv7 package fails.

If the abovePowerPC package will not work on your device, please download the latestppc-static package.The static package includes "static" binaries, that means, it includes binaries that have no external library dependencies andshould be run on your PPC device if the normal PPC package fails.

If you upgrade your NAS from DSM6 to DSM7, you should just download the new dsm7 package for your device.The old package and new DSM6 packages will not work anymore, since DSM7 changes a lot under the hood (no more root permissions for packages,minimum package version 7.0, etc.).
Just download the DSM7 package and install it from the Package Center as usual.

If, after upgrading to DSM 7, the old package is still installed, please uninstall it and install it again.

If you encounter any problems, please read thetroubleshooting section first.

• Open the Package Center app.
• Click onManual Install and upload the package you just downloaded.
  • Select AirConnect packages that should be installed
    • 
  • Insert IP (defaults to the synology primary ip) and the port for airupnp
    • 

Please use the older release for DSM 5 & 6:0.2.50.5-20210706

• Open the Package Center app.
• Click onManual Install and upload the package you just downloaded.

On DSM5 and some DSM6 devices: As this package is not an official Synology package you may have toAllow packages from any publisher(Go toSettings and set theTrust Level to "Any publisher".)

Do not forget tochange back theTrust level to "Synology Inc." for additional security.

• AirConnect-Synology and AirConnect Log File
  • TheAirConnect application logfile is located at/volume1/airconnect/log/airconnect.log (default location)
    • This is a symlink of/volume1/@appstore/AirConnect/log/airconnect.log
  • You can open it using the SynologyFileStation by navigating toairconnect -log
    • You can also open it after login with ssh to your NAS/Router:sudo /usr/syno/bin/synopkg log AirConnect
    • or by using a command-line utility like
      • more (more /volume1/airconnect/log/airconnect)
      • tail (tail -100 /volume1/airconnect/log/airconnect)
    • If you get apermission denied, you should use the full path, f.e.more /volume1/@appstore/AirConnect/log/airconnect.log
  • This log file is written by the AirConnect-Synology package.
    • All log entries of the AirConnect application (airupnp + aircast) are also written into this log file.
  • This is the first place to look for errors.
• Synology Service Log File
  • Thesynology dsm package logfile ist located at/var/log/packages/AirConnect.log
  • This logfile is used from DSM/Synology for all installation/uninstallation/update purposes
  • In general you will only use it for debugging purposes

Since Version1.8.3-20240403 The airconnect.log file will now be deleted if it exceeds a size of 50MBA one time backup in the same directory will be created namedairconnect.1.logThis backup will be deleted on the next start (useful if someone needs the old log for debugging).

Only available for DSM 7 packages!

You cannot view/edit the file with FileStation due to a limitation in synology DMS (Symbolik links) by default

Please keep in mind, that if you upgrade your existing AirConnect-Synology package no changes will be made to theairconnect.conf file.If you want to overwrite yourairconnect.conf configuration with the default one, please uninstall and install the package again.You can also copy the default values found below to your configuration file.

Starting with release0.2.50.5-20210801 you can customize the configuration of AirConnect-Synology by using the config file at/volume1/airconnect/airconnect.conf.
Pleasestop the packagebefore changing the configuration.
If you have edited the configuration while AirConnect is running pleaserestart the AirConnect package.

The configuration options and default values are:

AIRCAST_ENABLED=1AIRCAST_LATENCY="50:500"AIRCAST_LOGLEVEL="all=info"AIRUPNP_ENABLED=1AIRUPNP_LATENCY="50:500"AIRUPNP_LOGLEVEL="all=info"AIRUPNP_CONTENTLENGTH_MODE=0AIRUPNP_PORT=49154FILTER_AIRPLAY2_DEVICES="<NULL>,S1,S3,S5,S9,S12,ZP80,ZP90,S15,ZP100,ZP120,1.0,LibreWireless,Fitzwilliam,2.2.6,AllShare1.0"SYNO_IP="<your synology ip>"

Configuration options withMandatory = Yes must exist in the configuration. Options withMandatory = No are optional.

Please do not remove the optional configuration options you do not want to use, just set no value (empty value/string). Example:FILTER_AIRPLAY2_DEVICES=

If you want to edit yourairconnect.conf file from your computer using a network share (SMB),you need toallow symlinks in your SMB configuration on your synology NAS device.

Settings/Control Panel -File Services -SMB -Advanced Settings

Please activate both options:

It runs the AirConnect processes with the following options by default tuned for sonos:

/volume1/@appstore/AirConnect/airupnp -b [synology devicelocal ip]:49154 -l 50:500 -g 0 -x"/volume1/@appstore/AirConnect/config.xml" -o"<NULL>,S1,S3,S5,S9,S12,ZP80,ZP90,S15,ZP100,ZP120,1.0,LibreWireless,Fitzwilliam,2.2.6,AllShare1.0" -z -f"/volume1/@appstore/AirConnect/log/airconnect.log" -d all=info

/volume1/@appstore/AirConnect/aircast -b [synology devicelocal ip] -l 50:500 -x"/volume1/@appstore/AirConnect/config-cast.xml" -z -f"/volume1/@appstore/AirConnect/log/airconnect.log" -d all=info

OnDSM7 you can just change the parameterFILTER_AIRPLAY2_DEVICES in the configuration fileairconnect.conf.You could also remove these configuration parameter to allow all airplay2 devices.

To speed up the detection of Sonos/UPnP/DLNA speakers and to not discover speakers which natively supports airplay,this synology package will only include the devices mentioned in theList of supported UPnP Speakers.

If you have another UPnP based speaker that you want to be supported by this package which is not in the list below,please open anissue and let me know (Please tell me the product name(model name,model number etc.)), then i will include it to the default configuration.

With

-o <NULL>,S1,S3,S5,S9,S12,ZP80,ZP90,S15,ZP100,ZP120,1.0,LibreWireless,Fitzwillian,2.2.6,AllShare1.0

the sonos/UPnP speakers thatare natively supporting AirPlay or AirPlay2 will be ignored from AirConnect/airupnp and only the ones listed with-o will be used.

Since no new "non airplay" speakers (from sonos) will be released in the future, that should work in any case.So they will be not displayed twice in the list.

To find UPnP speakers, their device_description URL and the model number, follow the following steps.

If you are familiar with linux commands you could usetcpdump to discover upnp devices on your network.You can install tcpdump on any synology NAS by using he integrated synology diagnostic tools.

Just execute as root via SSHsynogear install to install the diagnostic tools.See documentation here:FAQ-synogear.
Synogear also installs a few other useful linux/busybox commands.I have installed the diagnostic tools (synogear) on every synology device that i own.

Change en0 to your network adapter name (wait a few seconds until the devices get discovered)

sudo tcpdump -vv -A -s 0 -i en0 host 239.255.255.250 and port 1900 | grep LOCATION

Then you need to find your device ip and catch the location URL.

With thecurl command (or the browser of your choice) you can then search for themodelNumber in the device xml configuration:

curl http://192.168.1.122:1400/xml/device_description.xml | grep modelNumber

S12 is a Sonos Play:1 in this example.

This modelNumber is the number that i need to extend the followingList of supported UPnP Speakers.

SeeCommand-Line Arguemts for more information about these arguments.

These default options should work for most of you but can also be changed by using aconfiguration file.

Both processes are running with the low-privilege userairconnect.

If you would like to tweak the AirConnect configuration you can also use the AirConnect configuration file.

Before continuing please check theofficial readme for more information.I'm not going to explain how it generally works here.

You cannot view/edit the file with FileStation due to a limitation in synology DMS (Symbolik links) by default

Hint: If you want to filter/include/exclude speakers in the configuration file orairupnpyou need to disable the default filter inairconnect.conf usingFILTER_AIRPLAY2_DEVICES=.See alsoairconnect.conf. The default filter will overwrite any filter in theconfig.xml file of airupnp.

By default the config file willnot being used as long as the file is not created (And you are not running on debug log level).

The file isnot created by default.

• Config File location for airupnp
  • /volume1/airconnect/config.xml
• Config File location for aircast
  • /volume1/airconnect/config-cast.xml

You can create each of these files manually or a reference version can be generated using the-i [config file name] command-line parameter.For the following example i am using the default configuration you can find above in theHow it works section.I am just change the-x parameter with the-i parameter.

Change the ip and parameters for your needs:

Example:

/volume1/@appstore/AirConnect/airupnp -b 192.168.1.249:49154 -l 50:500 -g 0 -i"/volume1/@appstore/AirConnect/config.xml" -o"<NULL>,S1,S3,S5,S9,S12,ZP80,ZP90,S15,ZP100,ZP120,1.0,LibreWireless,Fitzwilliam,2.2.6,AllShare1.0" -z -f"/volume1/@appstore/AirConnect/log/airconnect.log" -d all=info

After running this command, airupnp will be started until all needed information and devices are gathered,stopped and the resulted configuration will be written to the defined config file.

If you want to edit yourconfig.xml orconfig-cast.xml file from your computer using a network share (SMB) you need toallow symlinks in your SMB configuration on your synology NAS device.

Settings/Control Panel -File Services -SMB -Advanced Settings

Please activate both options:

Please check the originalPlayer specific hints and tipsfromphilippe44 for more information.

The upnp version is often used with Sonos players. When a Sonos group is created,only the master of that group will appear as an AirPlay player and others will be removed if they were already detected.If the group is later split, then individual players will re-appear.

You need to use the Sonos native application for grouping / ungrouping.

When changing volume of a group, each player's volume is changed trying to respect the relative values.It's not perfect and still under test now.To reset all volumes to the same value, simply move the cursor to 0 and then to the new value.All players will have the same volume then.You need to use the Sonos application to change individual volumes.

To identify your Sonos players, pick an identified IP address, and visit the Sonos status page in your browser,likehttp://192.168.1.126:1400/support/review.

ClickZone Players and you will see the identifiers for your players in theUUID column.

@chpusch has found that Bose SoundTouch work well including synchronisation(as for Sonos, you need to use Bose's native application for grouping / ungrouping).I don't have a SoundTouch system so I cannot do the level of slave/master detection I did for Sonos

Check theConfiguration section on how to apply the below tuning to the configuration.

Some of these speakers only support mp3 and require a modifiedProtocolInfo to stream correctly.

This can be done by editing theconfig file and changing<codec>flac</codec> to<codec>mp3</codec>and replacing the<mp3>..</mp3> line with:

<mp3>http-get:*:audio/mpeg:DLNA.ORG_PN=MP3;DLNA.ORG_OP=00;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=0d500000000000000000000000000000</mp3>

The build steps are done using GitHub Actions CI/CD. So it will be build automatically.
In case you want to build it locally, you can also use the following steps.

You need to install the following packages on your distribution:

• make
• shellcheck
• clone/download this repository

After that you can start the build process by runningshellcheck or directly with the build steps.

Grab version of your needed AirConnect package and set in variableRELEASE_VERSION

export RELEASE_VERSION=1.8.3

Go to thereleases page and grab the latest release or the version you want.
Download it and extract tosrc/dsm7/bin folder

Example for AirConnect1.8.3

wget https://github.com/philippe44/AirConnect/releases/download/1.8.3/AirConnect-1.8.3.zip -O src/dsm7/bin/AirConnect.zipcd src/dsm7/binunzip AirConnect.zip

cd src/dsm7make shellcheck

cd src/dsm7ARCH=arm make clean build

Possible values forARCH:arm arm-static armv6 armv6-static aarch64 aarch64-static x86 x86-static x86_64 x86_64-static powerpc powerpc-static

cd src/dsm7make clean build-all

You can find the built packages in thedist directory.

If you get an error message that the packagecannot be installed orupdated orstarted when updating AirConnect-Synology,pleaseuninstall the old version first (Package Center -> AirConnect -> Uninstall) and then install the new version.

Uninstalling also removes the old scripts, references and configurations (only the logfile remains).Sometimes it can happen that the problem is already fixed with this.

If the normal uninstallation also does not work, please cleanup the old package using SSH with root permissions:

• Delete old package (directory)

  • rm -rf /var/packages/AirConnect

• Delete old airconnect configuration directory

  • synoshare --del TRUE airconnect

• Delete old airconnect user(s) from a previous installation

  • synouser --del airconnect
  • synouser --del airconnect__PKG_

• Delete old airconnect group from a previous installation

  • synogroup --del airconnect

• After that please install the new package as found inhow-to-install

If you have a problem installing or using one of these packages and/or are stuck, please open anissue.

It would be very helpful for me if you tell me the synology device you are using,the package you have downloaded and upload the two logfiles mentioned in theLogfiles sectionor include the important parts from the logfiles in the issue.

If the package was installed successfully andairupnp andaircast are running and no strange problems will be shown in the logfilebut for you it is not working as excpeted,please consider opening anissue at the officiall AirConnect Repository.

Most of the problems with AirConnect are related to the local network configuration.AirConnect (and therefore Sonos/Chromecast) requireMulticast to function properly.You must ensure that the communication within your network supports multicast. Especially important is the communication:

Chromecast/Sonos speakers <-> (WLAN)-Router <-> (Switch/Firewall <->) Smartphone which is used

So make sure that multicast is allowed on your router,your switches and your firewall and configure settings like IGMP snooping + IGMP proxy so that the communication is guaranteed.

For testing, please deactive igmp snooping everywhere if you have activated it.

I have activated but properly configured igmp snooping and igmp proxy + different VLANs. It will work with AirConnect, if properly configured.

• When players disappear regularly, it might be that your router is filtering out multicast packets.
  • For example and testing, for a Asus AC-RT68U, you have to login by ssh and run
    • echo 0 > /sys/class/net/br0/bridge/multicast_snooping but it does not stay after a reboot.
• Lots of users seems to have problems with Unify and broadcasting / finding players.
  • Here is a guideubnt-sonos made by somebody who fixes the issue for his Sonos environment

For additional information, please check the following issues in the official AirConnect Repository:

• Best Practises for getting AirUPnP working in networks?
• Troubleshooting Steps for airupnp AirPlay Devices not Appearing?
• Devices disappear after ~1-2 Minutes
• Devices found, but not being added
• Unable to Connect to "device"

If you want to see more logs then change the AIRCAST_LOGLEVEL or AIRUPNP_LOGLEVEL fromall=info in/volume1/airconnect/airconnect.conf toall=debug and restart the package.

If you want to see more logs then change the-d all=info parameter inscripts/start-stop-status to-d all=debug and rebuild the package,theninstall it again.
