Ever get this to work? I am hitting the same issue in Angstrom on a beaglebone black. Have noticed this oddity, I cannot set the periodsize:
bbb: >>> a.setperiodsize(2048) 235L ???? even smaller sizes, like 128, fail. Maybe that's hard coded for the limited hardware and I need to find a usb sound dongle. PC with Ubuntu: >>> output.setperiodsize(2048) 2048L !!!!! Also see there is no mixer device, but that could be due to the limited hdmi audio, which works with aplay, etc. On Tuesday, March 6, 2012 9:40:14 AM UTC-5, Mik wrote: > > Dear all, > > I am a beginner with BeagleBoard (xM) and audio.
