From 549b170196948713aae2e1b578da8e8825b0b3b3 Mon Sep 17 00:00:00 2001 From: Dan Kovacek Date: Wed, 8 Apr 2026 18:28:53 -0700 Subject: [PATCH] sof-soundwire: rt711-sdca: add Headset Mic Switch to Headset sequences No sound captured in headset mic through jack on Dell Precision 5480, Ubuntu 24.04.4 LTS kernel version 6.17.0-20-generic Headset Mic Switch is a DAPM gate that must be enabled to connect the headset microphone input to the SoundWire capture pipeline. Without it the mic path is powered down regardless of the FU0F Capture Switch state, producing silence. Add Headset Mic Switch on/off to Enable/DisableSequence, matching the pattern already used for Headphone Switch in the Headphones device.
