Hi @Bogdan_Dorin,

Can you share some details on how your devices are connected to the network?

If you play to other endpoints do you experience the same behavior or do things work okay?

Are these Airplay devices grouped?

4

They are not grouped, other devices as bluesound node 2I or chromecast are working, it is something regarding software on ubuntu server, ffmpeg or libalsa, when the issue start the processor goes to maximum usage.

Moving to the Intel Nuc Rock (I have a spare celeron Nuc) the issue is not present.
So I suppose the issue is linked to alsa/ffmpeg versions on Ubuntu server 18.04 LTS.
