From: Geoffrey D. Bennett Date: Thu, 4 Sep 2025 15:53:51 +0000 (+0930) Subject: ALSA: scarlett2: Add Vocaster speaker/headphone mute controls X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cbd676874e64a2122edd03ba6a2406b24779df05;p=users%2Fhch%2Fmisc.git ALSA: scarlett2: Add Vocaster speaker/headphone mute controls Add support for the speaker and headphone mute controls on Focusrite Vocaster interfaces. Unlike other Focusrite interfaces, these mute controls are per-output, not per-channel. Signed-off-by: Geoffrey D.
