Subject: [PATCH] ucm2: da7213: Add ADC switch in HeadphoneMic2 sequences
Date: Fri, 27 Mar 2026 16:47:54 +0800 [thread overview]
Message-ID: <20260327084754.431898-1-le.qi@oss.qualcomm.com> (raw)
Enable and disable the ADC switch in HeadphoneMic2EnableSeq.conf and
HeadphoneMic2DisableSeq.conf to ensure headset microphone audio works
properly on Talos EVK with DA7213 codec.
Without this change, the headset mic path remains muted and capture
does not function.
