I can't play AAC file with Roon using Synology NAS DS218+

Hi @Pierre_Lafon and welcome to the forum.

Did you provide your own ffmpeg decoder?

Synology DSM7 App update (20220216) - Support for databases on USB and eSATA volumes

Hi @Bjorn_Konigsson, I’d guess, you need to place the ffmpeg binary in the RoonOnNAS/bin folder, as Synology’s own version does not provide all audio codecs. The new version might give you a hint, which ffmpeg version is used. the path of the used version is given in the RoonOnNAS.log.txt file, which is located in the RoonOnNAS directory of your selected database shared folder.

You can find suitable ffmpeg here.

Manually adding ffmpeg does not work

ok. Just for clarification: You’ll need ffmpeg for the amd64 architecture. When you download it from johnvansickles page, you’ll normally need to extract the archive at least once and sometimes twice (depends on the used application for this process). You only need to copy the file ffmpeg into the RoonOnNAS/bin folder. When done, you have to restart Roon Server in the app center in order to make use of the new provided ffmpeg.
