Bug Description
I've got a laptop with
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

since kernel -6 (but I don't remember the exact version, anyway the update was pulled in this week), my sound card once every minute (or better to say randomly, I don't understand what triggers it) emits a sound from speakers which sounds like 'TOC'.
I think this sound is caused by the power save options that were enabled in the module snd-hda-intel
This sound also comes out if the volume is mute, or set to 0%
