Comment 74 for bug 1935850

I still have this issue on latest kernel for 20.04 LTS:
5.11.0-46-generic #51~20.04.1-Ubuntu SMP Fri Jan 7 06:51:40 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I tried to update files in /lib/firmware/intel/sof from here : https://github.com/thesofproject/sof-bin
with no luck.

Please let me know if more info is needed - just have a Dummy device as others have.
Thank you
