This bug is awaiting verification that the linux-oem-5.14/5.14.0-1032.35 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.

[Fix] Backport codec patches and some i2c and acpi detection patches from mainline kernel and linux-next [Test] boot the patched kernel, run speaker test, both left and right channel could work well. [Where problems could occur] If it could introduce regression, it will be on soc wm_adsp codec drivers, since most of patch are adding new codec drivers, it will not touch existing codec drivers. If a machine with wm_adsp codec can't output sound or record sound, it means this SRU introduce the regression on wm_adsp driver, but this possibility is very low, since all patches are picked from mainline kernel.
