And please also upload the dmesg. BTW, how did you update, only update the pulseaudio or upgrade many packages? And what is the pulseaudio version now (checking it by running dpkg -s pulseaudio | grep Version). jorge2@jorge-Mate-20-4:~$ dpkg -s pulseaudio | grep Version Version: 1:13.99.1-1ubuntu3.2lp1869819 jorge2@jorge-Mate-20-4:~$ I update from http://ppa.launchpad.net/kaihengfeng/fix-lp1869819/ubuntu I'm sorry, I don't understand what you mean by "upload the dmesg. BTW", I know the command dmesq, what do you want me to do?

[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.
