My PC operating system is Windows XP Home SP3. Shortly after buying the PC I bought and installed a Philips Sonic Edge sound card and a set of VideoLogic 5.1 Surround Sound speakers with subwoofer. At the time I was a PC novice and my oldest son did the installation. All worked well until approx two years later when I reformatted the OS. After that although everything else works as it did I had a problem when testing the speakers via the Philips interface.The front left and right speakers have a reduced volume in comparison with the Rear L/R and Centre speakers even if I have the fader control at the top thereby cutting the sound from the rear speakers they seem to have the same reduced volume at any position. I mentioned this to my son at the time and he reckoned that the front speakers had just lost a bit of their efficiency. I believed this until yesterday.
I use VLC player for all audio and video playback and was playing about with the VLC preferences settings. Later I noticed that the sound on playback was very loud even at only one or two on the volume slider. I quickly realised that I must have done something to the VLC audio settings and on checking found that I had accidently changed the default audio output type in VLC from default to Win32 Waveout Extension Output. I changed it back to default and saved it then exited. That evening I watched a film and it was in the normal surround sound ie 5.1 speakers. Next morning on signing in I played some music and noticed that there was no sound coming from the rear speakers. I went in to the XP control panel > Sounds and Audio devices and checked that it was set at 5.1 Surround which it was. I then exited VLC player and reopened it with a video to find that all speakers were now working with sound coming from them. I opened up the Philips interface and did a test and found that both Front L/R, Rear L/R and Centre speakers now had equal volume. Today I find it has reverted to the previous mode with the front L/R having the reduced volume again. I tried unsuccessfully to recreate whatever I had done to get them to work properly but now realise that at least there is no problem with the front L/R speakers as I had previously thought but that it must be a configuration problem. Could anyone help me to get this sound card, the 5.1 speakers and Windows configured correctly in order for it all to work as it should?. Thanks in advance for any help offered.
