First, do a pactl list and see what state PulseAudio thinks its various components are in. It's likely they're stuck in a SUSPENDED state for some reason. I haven't configured pulseaudio on my Bone yet, but on my Pandaboard I had to change the /etc/pulse/daemon.conf file so that it used resample-method=speex-fixed-3 instead of speex-float-3.
If those ideas don't get you any further, try turning on more debugging information when you start up PulseAudio and give us a log dump. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
