Comment 18 for bug 884336

I'm seeing a similar issue with a similar setup. I've got a media center connected to a receiver via HDMI. Sometimes when I'm playing audio and power-cycle devices in the chain (TV, receiver, etc), pulse will stop playing audio. I don't get any errors or anything, and issuing pulseaudio -k will bring it all back.

I tried commenting out the module-suspend-on-idle module. It seemed to work at first, but I eventually got into a state where PA applications complained about not being able to play back, and audio went silent.

I think this could be an ALSA issue, but it's quite difficult to debug. Has anyone else come up with a solution to this problem?
