[PATCH] ASoC: amd: yc: Enable internal mic on MSI Bravo 17 C7VF

Posted by João Miguel 6 days, 13 hours ago

The MSI Bravo 17 C7VF routes its internal digital microphone through
the ACP6x. The machine driver only enables the DMIC for boards present
in the DMI quirk table, so on this model the internal mic is never
detected and no capture device is created.

Add a quirk entry matching the board's DMI identifiers so the DMIC is
enabled and the internal microphone works.

This doesn't apply against current code, please check and resend.

I see your patch was already applied by Mark in the original thread.

Just a reminder for your next submissions: when resending patches
please mark them clearly as [PATCH RESEND] so that it does not
confuse the maintainers.

Thanks,
