| Subject: [PATCH] ALSA: hda - fix digital mic selection in mixer on 92HD8X |
| codecs |
| |
| 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. |
