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- hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed- hirsute'.
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.

And this patch is already in the oem-5.10 kernel, for focal kernel, since focal kernel doesn't support soundwire audio, these 2 patches are useless for focal kernel. [Impact] The Dell precision 5760 is a TGL-H machine, and it has soundwire audio design, when running the hirsute kernel, the audio driver fails to load sof-firmware, then the whole audio fails to initialize and fails to work. [Fix] Backport 2 patches, these will remove hardcoded firmware name and allow load firmware according to the firmware name defined by pciid [Test] Booting the patched kernel, check dmesg, there is no errors about loading audio sof-firmware, playsound to spk and headphone, all worked well, record sound from internal mic and external mic, all worked well. [Where problems could occur] The patch remove the hardcoded firmware for all TGL soundwire machines, this could make the TGL soundwire machines fail to load the sof-firmware then the whole audio fail to work. But this possibiliy is low, since we tested the patches on different TGL soundwire machines, all worked well.
