Hi Wiza,

Please create a = bugzilla ticket at the below address and CC Cirrus Patches (patches@opensource.cirrus.c= om) to it, we will investigate the issue as soon as we = can.

https://bugzilla.kernel.org/

 

Please attach an acpi = dump and a full dmesg to the ticket. You may also want to check that = your system=E2=80=99s BIOS is updated to the latest = available.

 

The firmware tuning = files selected by the spkid differentiation include specifications of = the speaker hardware, the manufacturer has not shared details of a = spkid0 variant so it=E2=80=99s not a case of simply not creating an = alias.

 

Creating a public = Bugzilla allows others with the same laptop to find relevant information = pertaining to this issue.

Thanks,

-Simon
