Since the recent system upgrade i have a problem with audio output when using webrtc.

The problem is: When i use jitsi conference tool (either in chromium or as desktop app) i do not have audio output. This is also true in our internal conference tool (the vhs cloud in Germany) which is also based on webrtc. Before the system upgrade it worked flawlessly.
The audio output itself works, either with audacious as with vlc or when i play dvd, youtube … So, i presume the general alsa setup should be correct. Rather, i miss something in webrtc (?)
Using webrtc the only way to get audio is to use headphones.
Thanks a lot in advance for any pointer!!!
