PulseAudio crashes due to an assertion failure when ALSA's A52 plugin returns -EAGAIN. Reproducible: Always Steps to Reproduce: 1. Using /etc/asound.conf, add a PCM channel that uses the A52 plugin. 2. Disable hardware detection in PulseAudio and configure it to use this PCM only. 3. Start PulseAudio with "pulseaudio --system -vvv" Actual Results: Assertion failure. Expected Results: Successful daemon start. I manually removed the assertion line from the relevant PulseAudio source file. All apps that then attempted to use PulseAudio errored with "Entity not found."

I would also like to add that the PulseAudio team firmly maintains that ALSA is to blame here. A ticket for this is currently open in ALSA's tracker, but has been ignored for some time now. I have received no help from IRC, other then to contact alsa-devel, but I have received no help from them either.
Please add a link to the ALSA tracker ticket, and the output of emerge --info.
