Description of Issue
Playing ANY BBC radio stream for any BBC station on either AAC or MP3, I get occasional drop outs when playing to the Sonos.
However when playing to my DAC connected to my stereo I get no drop outs on the same streams.
Playing other stations (non BBC) to the Sonos end points I get no drop outs (e.g. jazz FM, Absolute, SomaFM etc)
I have found a work around as follows to remove the drop outs. this may help diagnose the issue.
- Play the MP3 128K stream not the AAC96k or AAC320K streams.
- in Roon device set up for the Sonos. on the advanced section, set "Max bits per sample (PCM) to 16 not 24.
- In the Sonos app, set the compression from “Automatic” to “Uncompressed”
This combination results in stability. Changing any of the above results in drop outs.
Note my Sonos are wired not wifi, and the network is 100% not at fault in this instance.
