Metallic distorted sound with OSS & USB soundcard

Hi folks,

I own an ESI U46XL, an USB interface audio. Initially used with ALSA/PulseAudio it was running fine but I read on the Internet that it would sound better with OSS - which is what I care the most about - so I decided to give it a try.

I followed the wiki page and it seemed to work just fine but I have a trouble with the sound: it is highly distorted and very metallic. I thought it could be a sampling rate problem, but when I play a 44.1kHz file, the output set in ossmix is automatically set to 44.1kHz so I don't see anything wrong here.

Here are my hardware and ossmix configuration for my usb audio interface (hope it can help):

[sclarckone@archLaptop ~]$ ossinfo -a
