** Description changed:
- This bug is for tracking purpose
+ Because we plan to remove sof-firmware related files from linux-firmware
+ of jammy and replace them with a debian package firmware-sof-signed, so
+ this SRU is not applied to jammy. I will submit another SRU to
+ firmware-sof-signed package later.
+
+ [Impact]
+ In the Dell oem project, we have many laptops which has sof dmic or
+ sof soundwire audio design, they need to load firmware and topology
+ files specific to ADL, otherwise the audio driver will fail to
+ initialize and the whole audio can't work.
+
+ [Fix]
+ Integrate the firmware and topology files from sof-firmware-v1.9.2
+
+ [Test]
+ Installed the patched linux-firmware and booting the patched kernel,
+ the audio work well, all output and input devices work normally
+
+ [Where problems could occur]
+ This SRU introduces new firmware and topology files for adl, it has
+ low possibility to introduce regression. If it could, it could
+ possibilily affect the other machines which also need to load firmware
+ and topology files, it could make the audio can't work on those machines,
+ but this possibility is very low, we have tested the SRU on many laptops,
+ no regression found.
