I've got some usb headphones with mic (Logitech clear chat USB (http://www.logitech.com/en-us/webcam-communications/internet-headsets-phones/devices/3621 actually, the version before this one, but basically the same thing)) that I use for teleconferencing. A few days ago certain audio stopped coming through, notably my teleconferencing.
As an example, there's a video of a muppet singing karaoke (Sam the eagle singing american woman, about as worksafe as a muppet can be) http://www.youtube.com/watch?v=pV4F46N21PA I can hear the music that the Sam is singing to, but not Sam himself.
If I use normal headphones it works fine. If I put these headphones on a different computer it works fine. I've rebooted several times. I've uninstalled the USB audio driver, rebooted, and let windows reinstall it (Logitech doesn't use it's own drivers, they use the generic windows drivers). No go.
I've played with the volume control that has (speaker, wave, sw synth, cd player, microphone), and not gotten anywhere. I've tried different USB ports.
Even so I'm guessing that there's something weird like mp3 audio is set to normal volume, but wmp audio is muted or something, but if so, I have no idea how to fix it...
I'm running XP, SP3, and I just now got all of the windows updates that I was behind on, and that hasn't helped either...
Help! Please! Thank you very much.
