Hello Johan, or anyone else affected, Accepted alsa-ucm-conf into groovy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/alsa-ucm- conf/1.2.2-1ubuntu5.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-groovy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-lib in Ubuntu. https://bugs.launchpad.net/bugs/1901922 Title: [SRU][Lenovo ThinkPad T14 Gen 1] No sound output device on startup Status in PulseAudio: Unknown Status in alsa-lib package in Ubuntu: Fix Committed Status in alsa-ucm-conf package in Ubuntu: Fix Released Status in alsa-lib source package in Focal: Fix Committed Status in alsa-ucm-conf source package in Focal: Fix Committed Status in alsa-lib source package in Groovy: Fix Committed Status in alsa-ucm-conf source package in Groovy: Fix Committed Status in alsa-lib source package in Hirsute: Fix Committed Status in alsa-ucm-conf source package in Hirsute: Fix Released Bug description: [Impact] On the machines with AMD Ryzen acp audio design, the audio can't work anymore after upgrading the libasound2 to ubuntu3(groovy)/ubuntu2.1( focal), this is a regression on libasound2 for those machines. the AMD Ryzen acp audio card needs to load ucm to work with pulseaudio, but this audio card doesn't have an independant ucm for it, it needs to link to an existing HDA-Intel ucm, the check_empty_configuration() needs to cover the situation that Linked is true, otherwise it will fail to load the ucm for the audio card. Even the audio card could load the ucm, the output is muted and the init output volume is too low if freshly install the OS on these machines. [Fix] Backport 1 alsa-lib patch to fix the failure of loading ucm on AMD Ryzen acp audio machines. Backport 4 alsa-ucm-conf patches to fix init mute and init output volume problem. [Test Case] Install the updated libasuond2, rm ~/.config/pulse/*; sudo rm -rf /var/lib/alsa/*; sudo sh -c 'echo b > /proc/sysrq-trigger' and run pacmd list-cards, we could see the pulseaudio load the ucm successfully and we could see the sound card is generated and all output and input devices are listed under sound card, but the init output is muted and the volume is very low if we manually unumte it. Now install the updated alsa-ucm-conf, rm ~/.config/pulse/*; sudo rm -rf /var/lib/alsa/*; sudo sh -c 'echo b > /proc/sysrq-trigger', the output is not muted anymore and the output volume is OK to most users. [Regression Risk] This could make the machines with sof audio driver fail to load ucm , then all audio function can't work as before, like the speaker can't output sound or the internal mic can't be found or can't record sound. But this possibility is very low, I tested this SRU on some machines with or without sof audio driver, all worked as well as before. After logging in, only a dummy device is available for audio playback (resulting in no audible playback). When running "pactl load-module module-detect" the sound card shows up, and playback works as expected. If pulseaudio is restarted with "pulseaudio -k" the playback device disappears again. Running the above command get things working again. If I change the following section in /etc/pulse/default.pa from: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect .else ### Use the static hardware detection module (for systems that lack udev support) load-module module-detect .endif To: ### Automatically load driver modules depending on the hardware available #.ifexists module-udev-detect.so #load-module module-udev-detect #.else ### Use the static hardware detection module (for systems that lack udev support) load-module module-detect #.endif Things start working as they should after running "pulseaudio -k".
