From 39ca594f809864dabb1756023018b3c0e2f721c2 Mon Sep 17 00:00:00 2001 From: Vitaly Rodionov Date: Mon, 22 Jan 2024 18:47:10 +0000 Subject: [PATCH] ALSA: hda/cs8409: Suppress vmaster control for Dolphin models commit a2ed0a44d637ef9deca595054c206da7d6cbdcbc upstream. Customer has reported an issue with specific desktop platform where two CS42L42 codecs are connected to CS8409 HDA bridge. If "Master Volume Control" is created then on Ubuntu OS UCM left/right balance slider in UI audio settings has no effect. This patch will fix this issue for a target paltform.
