Re: [Linphone-developers] No sound in video call

[Andreas Pretzsch]

Dear Mr. Beckert,

in the next days I'll investigate this problem with the help of Mr. 
Morlat, as it can be reproduced on my target platform with the new 
linphone 2.0.1, which made it worse compared to 1.7.

It indeed seems to be an ALSA problem, causally or side effect.

It would be interessting to know if you made any progress here or could 
provide any new findings.

Also I'd like to ask all other participants of the mailing list if they 
had similar issues.


Best regards,
  A. Pretzsch
