Sound issues on Asus AT3IONT-I

[Auliyaa]

Hi everyone,

I'm posting here because I'm experiencing some sound issues with my XBMC powered mediacenter. I got a lot of crackled noise on several of my music files and on almost every video files.

Note: I'm not using HDMI for audio playback, I plugged a USB Surround Sound Card to a 5.1 sound system. (And yeah I also tried to switch with another sound system x_x).

I've searched for a solution on several forums but I haven't been able to solve this. I've tried the following configurations so far:

Running XBMC on the following platforms

• Windows 7 64bits. I've tested XBMC 11.0 12.0 12.1 and 12.2
  
• OpenElec for ION Builds 3.0.6 and 3.1.6
  
• OpenElec for General Builds 3.0.6
  
• Arch Linux 64bits with the latest version of xbmc available on the official repositories.
  

I've tried several other players like Windows Media Player and my music/video plays fine. SO I guess this is a problem solely related to XBMC...

Changing the Audio Output settings in various ways
I've tried almost every combination of those settings, I also tried to use the HDMI output but the issue still remains.
I also tried to set the downmix level options to the minimum but no change.

To finish, you'll find below some extra informations about my system:

If anyone could have a hint about this issue, I would greatly appreciate it since having a bad sound on a Media Center is a real pain and I don't know what to do next :/
