Hi,
Currently, suspending the computer via pm-suspend (as done from HAL), causes the ALSA state to be stored and restored via alsactl. Here's what the hook looks like:
http://cgit.freedesktop.org/pm-utils/tree/pm/sleep.d/65alsa
Is this still necessary on recent kernels? Is there a list of drivers which properly maintain state across suspend/resume? We're trying to cut down on the amount of work done in userspace which slows down suspend cycles.
The all drivers with PM support should have do store/restore the mixer states. For such drivers, calling alsactl is just a waste of time.
I don't know who introduced it, but maybe it was a workaround...
