| Subject: ALSA: hda/realtek: Limit mic boost on T480 |
| |
| From: Benjamin Berg <bberg@redhat.com> |
| |
| commit 85981dfd6b0a0fd9ed87ca4a525981b67c21f098 upstream. |
| |
| The internal mic boost on the T480 is too high. Fix this by applying the |
| ALC269_FIXUP_LIMIT_INT_MIC_BOOST fixup to the machine to limit the gain. |
