MPlayer equalizer squawk

Hey y'all,

I'm trying the mplayer audio filter settings for the equalizer (equaliser) and it seems to produce a static sounding squawk.

This is an example config,

Your numbers are way too high I'd say. In my case, I need to enhance the higher frequencies a bit and use this:

Thanks for the reply.

Nod, I did notice that the 11's and 12's were crazy-high. I found the improvement when I fiddled the values earlier. But indeed I should've investigated, played, more.
OK, edit time...

The problem was I was comparing to eq-xmms values. Turns out eq-xmms, scales things on a -20 --> 20 scale for a dB scale -12~dB --> 12 dB.
HOWEVER
It still seems that even relatively, I need to scale mplayer down on a normalised view to get a similar effect.
There is no doubt that eq-xmms outperforms and is acceptable, where mplayer still gives an awful scratchy sound if you go to any reasonable adjustment.

I'd still very much like to know the relation of dB levels to the hardware via alsa...

Edit #2:
I can confirm that mplayer has the scratchy, squawky sound before it approaches the sound quality or adjustment amount of eq-xmms. In fact you can use the entire range of eq-xmms even if it does sound mucho distorted.

Anyone with more info?..
