Description

Audio is not functioning when PulseAudio (0.9.15) is in use; it seems to work fine if I kill PulseAudio. With PulseAudio running, I see lots of messages like this in /var/log/messages: 

Jul  9 21:18:13 localhost pulseaudio[3702]: alsa-sink.c: Error opening PCM device front:0: Device or resource busy
Jul  9 21:18:13 localhost pulseaudio[3702]: sink-input.c: Failed to create sink input: sink is suspended.

Output of alsa-info.sh is here:

This just means that you have a setup issue and some other application is accessing your devices directly, bypassing pulse. As this other app is using your device, pulse cannot access it at the same time.

You can find out what process is accessing your sound hardware by doing: fuser /dev/snd/*

This will list the process ids of the applications in question. You can find out what app this really is by doing ps up <pid from previous command>.

Hope this helps identify your setup problem. Feel free to reopen this bug if you find that this turns out to be a bug in pulseaudio.
