Dear Mr. Pretzsch,
I'm working on Linphone rel.1.6.0 on a Freescale ARM platform (with alsa 
driver) and I've seen same problems with video call: every time iMX 
starts the video call I've no sound (or few packets) upload.
I've tried to force codec selection but it doesn't solve.
When the caller is linphone 1.7 or a windows binary release on a 686 
host the problem can not occur, but often I've got same bug.
I've not deeply investigated this behaviour, but note that you have 
another different configuration facing same problems.
Maybe next weeks I'll let you know.
Regards,
Enrico
