No sound from BeagleBoard xM


My BeagleBoard xM has been installed with Ubuntu 10. All the functions

"Audio does not yet work on beagleboard XM." was indicated in this

I tried to upgrade the system to Maverick and unmute all the channels
in alsamixer, however, there is still no sound at all.

Did you install additional drivers or related packages? Also, are you
using pusleaudio?
