Bug description:
[Impact]
On some I+N machines (inlcuding lenovo and dell machines), after
setting the graphic mode to perofermance mode, and open the gnome
sound seting, run suspend/resume test, the audio devices will
disappear from UI, instead a dummy audio shows on the UI, and from
then on, the audio can't work anymore.
[Fix]
The root cause is after resuming, the pulseaudio try to recover the
PCM device, but at that moment, the devices nodes at /dev/snd/ are
not accessible yet sometimes, it will make snd_pcm_open fail and
the pulseaudio will calll unload_module to unload alsa audio card.
I cherrpicked a fix from upstream, the fix adds retry and pa_msleep(),
this will retry the snd_pcm_open() a couple of times if it fails.
[Test Case]
Install the pulseaudio wit this fix, set the graphic mode to
performance mode, open the sound setting, then run suspend/resume 90
times, after test check the audio devices on the UI, the speaker,
digital mic are still on the UI, and they could work well.
[Regression Risk]
Low, this SRU just add retry and pa_msleep(), if the snd_pcm_open()
doesn't fail, this patch will not introduce any change, if snd_pcm_open()
fails, it just retry a couple of times, so it will not introduce the
regression in theory.
