[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.
