Windows 7: 5.1 Setup Right Surround Playing Through Left Surround

Hello all,

I recently moved from XP to Win 7 Ultimate X64 and am experiencing some sound issues. For the record, everything worked just fine in XP. I have a Turtle Beach Montego DDL sound card and a set of Logitech X-540 5.1 speakers. The speakers are all connected to the sub which is connected to the soundcard via the standard analog connections. I have newest Turtle Beach Montego DDL Vista / Win 7 x64 driver installed.

When my Montego control panel is set to 5.1 mode the right surround channel is being routed through the left surround speaker. The left surround speaker plays both the left and right surround channels while the right surround speaker is completely silent. I switched the 2 surround speaker connections to verify that the right surround speaker wasn't dead and sure enough the right surround speaker played both the left and right surround channels while the left surround speaker was silent. Additionally, the X-540 speakers have a "Matrix Mode" which mixes stereo sound to all 5 speakers on the hardware level and all 5 speakers play when it is activated, which leads me to believe this is a driver and/or Windows 7 issue.

I've played with every Windows 7 sound option and Montego control panel option that I can find and absolutely nothing will fix this issue. When I run a sound test from either the Windows 7 "sound" setup or the Montego Control Panel the test tones for both the left and right surround play from the left surround speaker. I've reinstalled the driver but it didn't fix the problem. For now, I'm using the X-540 "Matrix Mode" with the speaker mode in the Montego control panel set to "2 Speaker" but the mix to the surround speakers sounds pretty bad and is less than ideal.



I'm looking for any help anyone can provide regarding this issue. It's bugging the Hell out of me.
