From fed7ad967a0bb12d5ae85759a63f40297bbd03fd Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Thu, 12 Jun 2025 13:11:06 -0500 Subject: [PATCH] mb/google/reef: Correct channel count for DMIC These boards only have 2 DMIC physically connected, and attempting to record from 4 channels vs 2 results in a large amount of background noise which drowns out the recording. Selecting the 2 channel DMIC shows audio on both channels and no noise. TEST=build/boot reef variants, test built-in mic under Windows and Linux.
