@sponsor-team, This is the debdiff for focal. And let's SRU this fix to groovy and focal first, because our oem project is waiting for the fix to be landed to focal.
And since groovy is not released yet, I don't provide the debdiff for groovy, and I already pushed the fix to git repo (groovy branch, focal branch, eoan branch and bionic branch). ** Patch added: "pulseaudio_13.99.1-1ubuntu3.5.debdiff" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1887610/+attachment/5392771/+files/pulseaudio_13.99.1-1ubuntu3.5.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1887610 Title: [SRU]There is no available audio entry in sound settings after execute suspend in 'Performance mode' Status in HWE Next: New Status in pulseaudio package in Ubuntu: Confirmed Status in pulseaudio source package in Bionic: Confirmed Status in pulseaudio source package in Eoan: Confirmed Status in pulseaudio source package in Focal: Confirmed Status in pulseaudio source package in Groovy: Confirmed 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.
