Poor sound quality at high frequency and volume

Hello,

I have a Turtle Beach Santa Cruz (cs46xx), running ALSA in mm-sources 2.6.2.

I've noticed that at high frequency and volume, sound quality really goes down and sounds... "staticy". This effect is really noticeable with songs with higher female vocals. (I'm using "Evanescene - My immortal" as a sample.)

I've tried turning down DAC and PCM, but no dice. It still sounds bad. I've tried the same file on my laptop by the way, which is running the same software (ALSA with i810 audio).

Anyone elso have this problem or have any suggestions?

I have the Santa Cruz also and have the same problem. I'm pretty sure the problem lies within the ALSA driver as I've heard people mention this before. If my PCM volume isn't raised over 80 i usually don't hear the static, but over that I do.

most soundcards start to get distortion about 80%.

In youre case it sounds like youre talking about clipping.
It could easily be an alsa issue (setting a gain value to high?), but if you can solve it by keeping the volume below 80%

I have the same card no problem, but I have to keep my PCM channel around 75%. Just in case you weren't sure PCM is different from normal volume. Double check that your PCM volume is around 75%, hopefully that'll work.

Hi

Just keep the volume on the computer below 80 and amplify via the volume control on the speakers...
