Severity: important
X-Debbugs-Cc: mpearson-lenovo@squebb.ca

Dear Maintainer,

Doing Linux enablement on Lenovo 2026 platforms and audio is not working
on many Pantherlake platforms.
On the kernel side SND_SOC_SDCA_CLASS needs to be enabled.

Would like this to be in place for kernel 7.0 and later please - it will
allow Debian users to have a better experience on newer HW.

Let me know if there's anything I can help with for testing.
