Trigger: On resuming a session from hibernate Expected behaviour: I should be able to output audio from the selected default device in Settings -> Sound, much as I was able to do so before hibernating. Actual behaviour: Unable to get any audio from M-Audio 1010LT. Going to Settings -> Sound and reselecting the device fails to enable audio output. Killing pulseaudio from terminal (pulseaudio -k) which causes a respawn fails to correct issue. Essentially it's high time we sorted out this Linux audio joke of a configuration. Many many people have spoken about and recognised the need to do this, but only Canonical & Ubuntu really have the power to do it. PulseAudio / ALSA / Jack constantly compete for exclusive access to sound devices, which is no wonder the spaghetti network fails on resume. I'd suggest binning Pulseaudio / Gstreamer etc entirely, and reducing audio management down to two layers: the driver, and the mixer. ALSA does both nicely. Develop a GUI mixer for ALSA as the standard Ubuntu desktop mixer, and develop a Pulseaudio like ALSA plugin that allows programs which will normally only talk to Pulseaudio, think that ALSA is Pulseaudio. Also force ALSA to select default sound device by name rather than by hw:# identity which can change on reboot.
