Summary: Background noise in master when no playing sound on
Asus A7N8X Deluxe (nforce 2)
Description:
Quoting http://www.nvnews.net/vbulletin/printthread.php?t=35148:
Every Asus A7N8X Deluxe Rev 2.0 Board has a problem with a weird "whining"
"whirring" or "buzzing" "static" noise coming out of the speakers AND out
of the motherboard itself.
When speakers are connected and the volume is turned up to normal levels,
the noise is very loud, approx 20% of the signal.
This noise appear when the card is not playing sound and there is low CPU
using. As soon as you play sound, noise stops. If you pause xmms or any
player, noise returns.
Muting all the channels does not stop the noise, but if you exec: "alsactl
power 0 off" &https://bugtrack.alsa-project.org/alsa-bug/view.php?id=161;noise
stops!, but you have to exec "alsactl power 0 on"
to use the card again. The driver could do the same than "alsactl power 0
off" when it isn't playing sound.
If you use the lastest nforce drivers (1.0-0283 or newer) noise stops.
