It doesn't show any process using audio, yet it still shows device 100%
used (see attached powertop.html).
I found a hint though, if I try to rmmod all my snd related modules I
get this error:
ERROR: Module snd is in use by thinkpad_acpi.
Well now, acpi is supposed to help save power, not prevent it, right?
But even if I remove thinkpad_acpi powertop still reports 100% usage,
but I can rmmod all the 'snd' devices now.
There's one more hint in dmesg:
input: HDA Digital PCBeep as
/devices/pci0000:00/0000:00:1b.0/input/input13
Could it be this one thats keeping the device busy 100%?
