Subject: [PATCH] ALSA: hda/realtek: Limit mic boost on T480
Date: Wed, 14 Feb 2018 13:29:39 +0100 [thread overview]
Message-ID: <20180214122939.10069-1-bberg@redhat.com> (raw)
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.
