Subject: ALSA: hda - fix digital mic selection in mixer on 92HD8X codecs
From: Vitaliy Kulikov <[email protected]>
commit 094a42452abd5564429045e210281c6d22e67fca upstream.
When the mux for digital mic is different from the mux for other mics,
the current auto-parser doesn't handle them in a right way but provides
only one mic. This patch fixes the issue.
