Hello,
I am attempting to use the analog audio out /headphone jack on a Pandaboard.
All
the builds I an built from git since the mediastreamer fixes were in
place have worked fine howver I haven't actually tested calling.
Audio with mediastreamer isn't working here is part of the log.

also note that I can get ffplay to
play .wav files with just the defaults i.e ffplay test.wav and so on...
however it fails on a video with surround51 as it apparently fails to
convert it to plain stereo for some reason.
play surround:

I'd apreciate an ideas about
fixing this I believe it is a linphone problem as it finds the card but
passes incompatible paremeters. And as I also mentioned ffplay can
definitely play mono 16 bit audio..
I may end up just using a USB audio dongle but I'd rather not and I'm rather pressed for time.
