Logitech z906 and SB Omni surround

[diyeys]

Hi,

 

I have a logitech z906 5.1 system and recently I got a SB Omni surround for my laptop. The problem is that 5.1 sound is not working. When I do the logitech test directly from the console, all the speakers are working fine (the sound is coming from the right speakers). If I do the test on Windows 10 or SBX Studio and I click on the front speakers the sound is mixed with the rear speakers as well (like if I click on front left, sound is coming from front left and rear left), but if I click on any rear, sub or the center speaker there is no sound. If I play spotify or a game, all the speakers are working.

 

Things I checked:

• I am using a 6 channel analog cable and it is connected correctly
• Speakers on Windows 10 are set to 5.1
• Speakers on SBX Studio are set to 5.1
• I have the latest drivers

Any idea on what's the problem? Thanks
