Subject: [PATCH alsa-ucm-conf 3/3] bytcr-rt5640: Add support for controlling a speaker-mute LED
Date: Fri, 7 May 2021 15:11:39 +0200 [thread overview]
Message-ID: <20210507131139.10231-4-hdegoede@redhat.com> (raw)
In-Reply-To: <20210507131139.10231-1-hdegoede@redhat.com>
Add support for controlling a speaker-mute LED using the new snd_ctl_led
kernel module for generic mute LED control.
Tested on a HP Pavilion X2 10-n000nd and a HP Pavilion X2 10-p002nd both of
which have a detachable USB keyboard with a speaker mute LED embedded in
the audio-mute button.
