no sound output

[jpakkane]

One issue is that if you use an external HDMI connector, apps start using that, even though the default in audio settings is heaphones or speakers. This is not a pbpro issue as such, the same happens sometimes on desktop Linux. The difference is that the audio settings widget has an option to switch audiostreamer per app to a different output. The pbpro mixer does not have it, maybe stretch is too old to have this functionality.

I managed to fix this once for Chromium but I can't remember the exact steps I took, so now Youtube sound works on Chromium but not on Firefox.
