| Subject: ALSA: hda - Fix noise on Gigabyte Z170X mobo |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 0c25ad80408e95e0a4fbaf0056950206e95f726f upstream. |
| |
| Gigabyte Z710X mobo with ALC1150 codec gets significant noises from |
| the analog loopback routes even if their inputs are all muted. |
| Simply kill the aamix for fixing it. |
