From: Cezary Rojewski Date: Mon, 9 Mar 2026 09:16:04 +0000 (+0100) Subject: ASoC: Intel: catpt: Do not wake DSP just for volume setup X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=150badf73e9a10cf646d07353b41117ea90f67ae;p=thirdparty%2Flinux.git ASoC: Intel: catpt: Do not wake DSP just for volume setup With the new control-operations in place, the controls no longer wake the DSP just for the sake of updating volume (or mute) settings on the firmware side. The values are cached and actual update occurs only when streams are being opened for streaming or are already running. In those cases the DSP must already be woken up and we avoid unnecessary power consumption.
