This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[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.
