From 3d25aaf71fe0fb5476ae485f9855cf74b87a5474 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 4 Sep 2022 09:27:50 +0200 Subject: [PATCH] ALSA: hda/sigmatel: Keep power up while beep is enabled [ Upstream commit 414d38ba871092aeac4ed097ac4ced89486646f7 ] It seems that the beep playback doesn't work well on IDT codec devices when the codec auto-pm is enabled. Keep the power on while the beep switch is enabled.
