Last week a friend of mine gave me his old Logitec z5300e THX certified, 5.1 speakers that were made by Logitech. Now, I know that they're ten years old, but I do know one thing: they work. I plugged in all the color coded 3.5mm jacks (four in all) in their color coded ports. Then, I went to the audio menu in Windows (I am running Windows 8.1) to the IDT audio source that I am using. Speakers/Headphones IDT Audio Codec. I right click and hit configure. I select 5.1. I test the speakers in 5.1 and only the front left and right speakers seem to work. Then, I decided I'd see if the system actually worked so I put on a movie. The movie contains up to 5.1 audio channels, and played fine through all the speakers (I actually picked them up and listened to each of the five speakers separately.) They all worked. Then I went to choose the 5.1 option in the audio selection menu of VLC. Turned to 5.1, and no audio from the center speaker, just the left, right, LFE, rear right/left speakers. Odd. Then I went back to windows audio control panel, back to Speakers/Headphones, and changed the sound from 5.1 to stereo. I played the film again. The speakers still worked in stereo. I turned the 5.1 surround mode on VLC and they all worked (albeit very low sound, almost impossible to hear.) What's the matter with my sound card? The drivers are up to date, as I made it a point to download the lates IDT driver from HP just yesterday from the HP website. Nothing seems to work, and I cannot find any posts about this anywhere. I'd appreciate any help, or advice I can get.
