[alsa-devel] How to test suspend ?
I couldn't make s2ram work on my machine and /sys/pci/.../power/state virtual files were removed one year ago. How can I test suspend/resume ?

See Documentation/power/states.txt
$ cat /sys/power/state
^^^^ nothing.

Cat does nothing because it doesn't change the current state. It should return:
standby mem disk
if the kernel is built to handle power management. If it does return any of these values, to change state you would type (as root): echo mem >/sys/power/state # suspend to ram # or echo disk >/sys/power/state # suspend to disk (hibernate).

It is... and /sys/power/state is supposed to be "mem" only. But since it doesn't work, is there another way to test suspend/resume of the soundcard ?
