Hi, I have windows vista 64 bit SP1. My sound card is an integrated Realtek HD 5.1. Picked up the Logitech x-540 speaker system yesterday and installed them today. While doing the test. I can not get the front 2 speakers to work as the front L/R speakers. They will only work under 7.1 as the Surround sound side speakers. Every other speaker works in its correct spot during test. Supposedly its only a 5.1 card. So why does it have a 7.1 setting on the sound setup. Hate to have to take these back as they were a good deal. Do I have a bad channel on my brand new computer sound card? Any idea on what it could be? Thanks in advance.
I had the same problem and all I had to do is move the green speaker wire for the output to the other green jack. Your card is probably set up for 7.1 and you have your speaker wire hooked into the 7.1 slot and not the 5.1 which is why the PC recognizes the FL and FR speaker as SL and SR.
Install the new version of your driver and of course uninstall the current version. After uninstalling the driver and reboot it to automatically reinstall it, the audio still may not work. Amazingly though, sometimes after putting the system in hibernate mode and coming back, the audio worked.
Hope it helps, if it doesn't , noaudiooutput.com have other suggestion. I used their solution and it works now.
