Comment 767 for bug 1958019

Looking more closely at your alsa-info... You have:
/sys/bus/acpi/devices/CLSA0102:00/status

I didn't even know the CLSA0102 existed! Just the CLSA0100 and the
CLSA0101. I don't think that's supported at all at this point. You might
try reaching out to Cirrus Logic. I think that's your best bet. There's
certainly nothing I can do. Sounds like the CLSA0102 's are strictly for
your the woofers?

CLSA0102 is almost certainly going to fall under cs35l41 and like the
CLSA010/1, it would likely need a custom code path.

Really wish Lenovo would play more nice with us. Yes, they have Linux
specific offerings, but like most of you, I'm not interested in those.
And in case anyone from Lenovo is listening... I'm not personally
interested in getting ANY Lenovo support for Linux. I just want my
hardware to work.
