Ok.. now that I'm home, I don't have an /etc/asound.conf nor an ~/.asoundrc, so unless it's getting set someplace I don't know about, I believe I'm routing through alsa with aplay. >> When you run that command (and it's "playing"), can you paste the output >> of "pacmd ls"? This might offer some clues. I grabbed a 30 sec wav file this time, verified that I could still hear it through aplay directly, and the captured the "pacmd ls" while it was playing using this command: paplay --device='alsa_output.platform-soc-audio.default-mapping-output' --volume=65537 record.wav And here's the output: http://pastebin.com/diLJiquq This is pa with the ucm patches..

I'm going to reset my environment back to a clean slate. I've made many changes trying to debug this, so I wanna make sure I haven't made things worse doing so. It's the same story from a completely refresh build, but I wanna for sure go back to a vanilla pa for now. I'll re-test once it's put back together. Shawn
