From a337c355719c42a6c5b67e985ad753590ed844fb Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 30 Nov 2023 16:13:21 +0100 Subject: [PATCH] ALSA: hda: Disable power-save on KONTRON SinglePC It's been reported that the runtime PM on KONTRON SinglePC (PCI SSID 1734:1232) caused a stall of playback after a bunch of invocations. (FWIW, this looks like an timing issue, and the stall happens rather on the controller side.) As a workaround, disable the default power-save on this platform.
