** Description changed: - This is tracking purpose + This fix is only for oem-5.6 kernel, the groovy 5.8 kernel doesn't + support soundwire audio at all, Intel said the linux-5.10 kernel + will have a good support for soundwire audio, so this SRU is + meaningless for groovy 5.8 kernel. + + + [Impact] + We enabled a new Dell TGL machine, the audio on this machine doesn't + work, the codec on this machine is soundwire bus connnected. + + [Fix] + With Intel's help, we need to backport some patches from upstream + kernel and linux-next kernel. + + [Test Case] + Boot the kernel, check with dmesg and aplay -l/arecord -l, the audio + card registered and speaker, headphone, mic and internal mic all + registered and worked. + + + [Regression Risk] + This could make the Dell cml soundwire audio fail to work or make + some sof dmic machines fail to work, but this possibility is very low, + we have tested this patchset on Dell cml soundwire audio machines and + some hp and lenovo dmic machines.
