Hi Takashi,

since you have patched the source code for the control of the Mute LED
on HP Pavilion DV7, I could test it for a longer time.

Everything works fine - except shutdown of the computer. I found out,
during the shutdown process a short loud hum occurs. This hum is
independ of volume and it come also, if sound muted.

I don't know whether this nomal (expected) or anything else is not 100 %
OK. What's your opinion ?
