'Twas brillig, and Gene Heskett at 15/04/10 14:44 did gyre and gimble:

Yup a bug indeed. It seems like a case of another bizarrely named
driver-specific control that generally mucks things up for us!
In order to test the fix, can you try adding the following lines to then
[Element Audigy Analog/Digital Output Jack]
switch = off
Then restart PA. That should tell it to turn that switch off and thus
prevent the problem.

PA will open the sound device when something wants to play and then it
will shut it down again after about 2s of inactivity. This background
hum is likely a product of having the device open.

There are probably various things that ultimately need to be exposed via
PA's mixer systems to get this fully supported. This is likely something
for another day/thread tho' :)

Indeed. If you could let me know if the above mixer-path fix solves the
problem fully for you, that would be great (ideally, you'd stop PA, run:
amixer -c0 set "Audigy Analog/Digital Output Jack" on
then start PA and run:
amixer -c0 get "Audigy Analog/Digital Output Jack"
just to make sure that PA has indeed turned it off for you :)

No worries :) Glad you can now enjoy the sound on Mandriva :D
