Comment 5 for bug 300290

Confirm on Kubuntu Intrepid AMD64 with playing audio on A2DP Bluetooth device:

I: sink-input.c: Created input 4 "Simultaneous output on ALSA PCM on bluetooth (bluetooth) via DMA" on alsa_output.bluetooth with sample spec s16le 6ch48000Hz and channel map front-left,side-left,front-center,front-right,side-right,lfe
I: module-alsa-sink.c: Starting playback.
E: module-combine.c: Assertion '!op->outq_rtpoll_item' failed at modules/module-combine.c:584, function sink_process_msg(). Aborting.

Upgrading to 0.9.13 (from https://launchpad.net/~racb/+archive ) didn't help me, the error is:

I: sink-input.c: Created input 3 "Simultaneous output on bluetooth" on alsa_output.bluetooth with sample spec s16le 2ch 44100Hz and channel map front-left,front-right
