From 100bb38c19df9ee30bde75b41c71266703d4d56d Mon Sep 17 00:00:00 2001 From: Cryolitia PukNgae Date: Fri, 22 Aug 2025 20:58:08 +0800 Subject: [PATCH] ALSA: usb-audio: Add mute TLV for playback volumes on some devices commit 9c6182843b0d02ca04cc1d946954a65a2286c7db upstream. Applying the quirk of that, the lowest Playback mixer volume setting mutes the audio output, on more devices.
