I cant get libvlc_audio_set_channel to work, The function call result is -1, also libvlc_audio_get_channel fails and returns 0.
I am using vlc 1.1.10. Is there a known issue with these functions ?

don't know, i never tried those. Try with vlc 2.0

I tried 2.0 same results.
Any ideas what may be the problem ?

I've just tested with libvlc 1.1.12, it works fine.
How are you calling them ?

Those functions works only during playback.
If you call them before or after playback, they won't work, and libvlc_errmsg will return "no audio input".
