Subject: [PATCH] ALSA: hda/realtek: Limit mic boost on Positivo N15RPE-S
Date: Wed, 5 Aug 2026 12:45:18 -0300 [thread overview]
Message-ID: <20260805154518.19093-1-edson.drosdeck@gmail.com> (raw)
The internal mic boost on the Positivo N15RPE-S is too high.
Fix this by applying the ALC269_FIXUP_LIMIT_INT_MIC_BOOST fixup to the machine
to limit the gain.
