For some cards these noises can be suppressed in software, however for others this appears not to be possible (according to some HDA driver devs at least, as discussed a Plumbers conf). It would be nice if we could have a blacklist in the kernel that makes sure power saving is only enabled for those where this plopp sound is known to not exist.

And I guess I agree.

Every release we try to enable the power savings and each time we end up disabling it. Also, I've got a machine that turns the speaker LED orange to indicated the sound is muted.... and that happens when we turn off the power to the card even though we're not really muted.

Any default behaviour is not ideal in this case, because: a) if this function is off - it might be obsolete with new HDA driver code b) if this function is on - cracks on hw on/off Perhaps, a mixer control like "Power Save" might be introduced, so users can touch this behaviour in a GUI.

Uh, I dont think forwarding this problem to the user really brings us forward. We could add a couple of rules for this udev. I am pretty sure I can convince Kay to accept rules into udev for this, although this looks a like a lot of work to maintain... Alternatively this could be maintained as part of the alsa mixer init db?

This bug isn't exactly "sound doesn't work at all" but it is listed on Common Bugs and is apparently fairly visible. Nominating as F13Target.
