Title: Make digital mic on the AMD Renoir machines work under gnome desktop Status in alsa-lib package in Ubuntu: New Status in alsa-ucm-conf package in Ubuntu: New Status in pulseaudio package in Ubuntu: New Status in alsa-lib source package in Focal: New Status in alsa-ucm-conf source package in Focal: New Status in pulseaudio source package in Focal: New Status in alsa-lib source package in Groovy: New Status in alsa-ucm-conf source package in Groovy: New Status in pulseaudio source package in Groovy: New Bug description: [Impact] On the LENOVO AMD Renoir machines, there is a digital mic directly connected to the APU instead of the codec, so there are two separate sound cards in the system, one is for analogue codec driven by hda driver, the other is for the dmic driven by ASoC acp driver. The current audio stack (pulseaudio + alsa-ucm-conf + alsa-lib) doesn't support this design yet, it could support all audio devices on the codec well, but it doesn't support that dmic well. In the gnome-control-center, the dmic becomes two input devices: analog input and multichannel input, and users can only record sound from analog input, the multichannel input can't function at all. Besides this issue, there is another issue, after users plug an external mic, the external mic can't replace the dmic automatically, this gives users a bad experience since this behaviour is different from the other audio designs.

On other machines: Boot the system with all updated packages or partial updated packages, check all input devices and output devices, they worked the same as before. this SRU doesn't bring any impact on other machines. [Regression Risk] Low For alsa-ucm-conf, this SRU adds two new folders and only minimum changes on existing folders, and these changes are under control and are for supporting acp driver. For alsa-lib, this SRU only adds the patches to support the ucm 3, and nearly all changes are in the ucm folder. there is no external ABI or API changes For pulseaudio, this SRU only integrate 3 patches, and 2 of them are for auto switching, and they are small patches and already upstreamed. the left patch are specific to Renoir audio, it will not bring impact to other machines. Also, we tested these changes with below machines: A LENOVO AMD Renoir laptop, all audio function works and no regression found A DELL laptop with intel dmic, all audio function works and no regression found A DELL laptop with intel soundwire audio, all audio function works and no regression found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1889217/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
