Date: Wed, 17 Feb 2021 18:31:57 +0100 Message-Id: <20210217173158.3122868-11-benjamin.tissoires@redhat.com> In-Reply-To: <20210217173158.3122868-1-benjamin.tissoires@redhat.com> References: <20210217173158.3122868-1-benjamin.tissoires@redhat.com> MIME-Version: 1.0 X-Scanned-By: MIMEDefang 2.79 on 10.5.11.12 Precedence: bulk List-ID: X-Mailing-List: linux-input@vger.kernel.org From: Roderick Colenbrander The DualSense controller has a built-in microphone exposed as an audio device over USB (or HID using Bluetooth). A dedicated button on the controller handles mute, but software has to configure the device to mute the audio stream. This patch captures the mute button and schedules an output report to mute/unmute the audio stream as well as toggle the mute LED.
