how to get rid of heavy distortion from the speakers?

[RotatingNut]

Greetangs bredren,

It used to be that

Code:

[font=monospace][color=#000000]# amixer sset 'DAC Stereo Enhancement' 0[/color][/font]

Vastly reduced distortion from the speakers. It now only returns

Code:

[font=monospace][color=#000000]amixer: Mixer attach default error: Host is down[/color][/font]

and distortion is pretty bad atm. What to do?

Hi,

so I double checked the amixer commands that used to lower the 'DAC Stereo Enhancement' setting. If run as a normal user, amixer returns a different error message, which hints at a missing control entry for that DAC enhancement.

Code:

amixer sset 'DAC Stereo Enhancement' 0

returns:

Code:

amixer: Unable to find simple control 'DAC Stereo Enhancement',0

This can be confirmed by listing all available simple controls

Code:

amixer scontrols

which now only returns two entries:

Code:

Simple mixer control 'Master',0
Simple mixer control 'Capture',0

Seems like the 'DAC Stereo Enhancement' control entry no longer exists. I'll dig a little deeper into this, but at least I think I found the general problem :D

UPDATE:

Ok, I think I got it to work:

Code:

amixer -c 0 sset 'DAC Stereo Enhancement' 0

does the trick.
