I tried mainline daily build 6.9.0-060900rc4daily20240420-generic. (Does it include commits that came a few hours before?) The microphone appears to be an acp63 device. Both snd_pci_acp6x and snd_pci_ps are loaded. Is the next step to blacklist snd_pci_acp6x? kernel: https://kernel.ubuntu.com/mainline/daily/2024-04-20/amd64/ commits: ASoC: amd: yc: Revert "add new YC platform variant (0x63) support" https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/noble/commit/?h=master- next&id=c58513355783d99af76c5b49e22cc4d275268d81 ASoC: amd: yc: Revert "Fix non-functional mic on Lenovo 21J2" https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/noble/commit/?h=master- next&id=575642e9cdf5ce526822a63daacb22802e4d64cd $ cat /proc/asound/cards 0 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0x785c8000 irq 90 1 [Generic_1 ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0x785c0000 irq 91 2 [acp63 ]: acp63 - acp63 LENOVO-21K5CTO1WW-ThinkPadP14sGen4 $ sudo lsmod | grep snd_pci snd_pci_ps 24576 0 snd_amd_sdw_acpi 16384 2 snd_sof_amd_acp,snd_pci_ps soundwire_amd 45056 2 snd_sof_amd_acp,snd_pci_ps snd_pci_acp6x 16384 0 snd_pci_acp5x 16384 0 snd_pcm 196608 14 snd_sof_amd_acp,snd_hda_codec_hdmi,snd_pci_acp6x,snd_hda_intel,snd_hda_codec,snd_sof,snd_ps_pdm_dma,snd_compress,snd_soc_core,snd_sof_utils,soundwire_amd,snd_hda_core,snd_pci_ps,snd_pcm_dmaengine snd_acp_config 20480 9 snd_rn_pci_acp3x,snd_pci_acp6x,snd_pci_acp5x,snd_sof_amd_rembrandt,snd_sof_amd_vangogh,snd_sof_amd_acp63,snd_acp_pci,snd_pci_ps,snd_sof_amd_renoir snd_soc_acpi 20480 3 snd_sof_amd_acp,snd_acp_config,snd_pci_ps snd_pci_acp3x 16384 0 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2062412 Title: No input through internal microphone (Ryzen 6000) Status in linux package in Ubuntu: New Bug description: The microphone in a Thinkpad P14S (AMD) Gen 4 stopped working after updating from 23.10 to 24.04 Beta with kernel 6.8.0-22-generic. This is a known problem and a patch may be included in kernel 6.8.3. Is it possible to backport this patch? Or is the plan to wait for a kernel update? It would be good use the microphone in 24.04.
