Windows 7: Windows system volume only controls left channel

Windows system volume only controls left channel

I am using a Xonar ST on Win 7 64bit......All of a sudden I noticed I was only getting sound on the right side. I reseated the card, reseated all of the connections, and changed the power connection from the PSU, and made sure on board audio was disabled.

I went into the control panel and balanced the audio....Left was set all the way down for some unknown reason. The volume on both sides will work at the proper level provided there is a separate control.....

The main system volume on the keyboard still only affects the left side. If I open winamp, the volume slider will control both left and right equally (provided the system volume is maxed out); turning down the system volume will leave the right channel at whatever level the winamp volume slider is set at.

I tried the latest driver, also tried the Uni driver. I also deleted the hsmgr file in windows/syswow64 that I saw people complaining about. I reinstalled the driver and hsmgr32 and hsmgr64 came back and are running at the same time. I unchecked them from msconfig so they do not start, but nothing has changed. Is this a driver problem or is there some other windows conflict. Since the programs seem to be able to individually control the volume I am thinking this is windows related. If I open youtube, the youtube volume slider controls both left and right. Does this have something to do with the soundcard exclusivity settings?

Is this a registry problem? It's like the volume is only monaural.

Thanks

Try the Windows uninstall/reinstall. Go to the Device Manger, in the Sound section RIGHT click on the entry for the Xonar to highlight it and then LEFT click on "Uninstall". DO NOT uninstall the drivers. Restart the PC and when Windows starts it will detect and reinstall the sound. This will correct any Windows corruptions with the sound card.

You mention that you use keyboard to control the sound volume - have you tried uninstalling the keyboard driver(+re install)?

I got it to work using an older 1.64 UNi driver....not sure why it stopped in the first place, but I will keep the windows uninstall in mind for next time. There are 3 separate sound devices/drivers running at a time on this machine and it was difficult to get everything working within windows the first time.
