---------------
I've also had another assertion failure, not sure when that happened (suspend/resume perhaps?)
ERROR:streamwidget.cc:94:void StreamWidget::setVolume(const pa_cvolume&, bool): assertion failed: (v.channels == channelMap.channels)
Bail out! ERROR:streamwidget.cc:94:void StreamWidget::setVolume(const pa_cvolume&, bool): assertion failed: (v.channels == channelMap.channels)

letting you reassign if you feel it's more appropraite over there.
