Hi,

since quality of the built-in audio jack on the raspberry pi is horrible so I use a USB sound
card which works fine. But I have no sound when playing a video with omxplayer.

Is it possible to add ALSA audio output support using (using libao) ?

Cheers,
Ruben

No, omxplayer relays on OpenMAX and the video/audio syncronization from OpenMAX.

Is it possible to drive the USB sound card from OpenMAX ?

I thought about passing the audio buffer from the demuxed stream to libao - so this would definitely not work out?

If you implement the video/audio sync accurate, it could work.
