Subject: [PATCH] ALSA: hda: Disable power-save on KONTRON SinglePC
Date: Thu, 30 Nov 2023 16:13:21 +0100 [thread overview]
Message-ID: <20231130151321.9813-1-tiwai@suse.de> (raw)
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.
