[Kernel-packages] [Bug 1935850] Re: Dell XPS 17 (9710) PCI/internal sound card not detected
I have the same problem with HP EliteBook 840 G6 fix: "options snd-intel-dspcfg dsp_driver=1" works but mic is broken -- 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/1935850 Title: Dell XPS 17 (9710) PCI/internal sound card not detected Status in linux package in Ubuntu: Fix Released Status in linux source package in Hirsute: Fix Released Status in linux source package in Impish: Fix Released Bug description: This patch is for soundwire audio, and only ubuntu 5.11-generic and later kernels support soundwire audio driver, so this patch is not sent to groovy and focal kernels. For oem-5.10 and oem-5.13 kernels, since this bug is not from OEM project, it is not urgent to merge this patch to OEM kenrels, after the patch is in the hirsute and impish kernels, the oem kernels will have this patch when syncing with generic kernels. [Impact] On the Dell XPS 17 (9710) machine, the audio card is not detected when booting hirsute or impish kernels. So the audio doesn't work on this machine with ubuntu linux 21.04 or 21.10. [Fix] Backport a upstream patch, this will set the correct codec config for this machine: rt711 for headset, dual rt1308 for spks and rt715 for internal mic. [Test] Booting up with the patched kernel, the audio card is detected, test internal speaker and internal mic, all work well, plug a headset, the headphone and external mic work well too. [Where problems could occur] This change only applis to the Dell machines with the DMI_PRODUCT_SKU equals to "0A5D", if this could introduce the regression, it will make the audio (speaker, internal mic and headset) can't work anymore on the Dell machine with that PRODUCT_SKU, but this possibility is very low, and we tested the patch on the machine, so far no regression is found. No audio/mic from internal speakers/build in microphone running Ubuntu 20.04, 20.10 or 21.04 . Can connect via USB headset and audio will work. Tried suggestions from Dell XPS 17 (9700) but this is the new model and fixes do not work. Currently running 21.04 with proposed. Have tried hirsute-proposed (5.11.0-24-generic) with no luck.
