David- have you looked to see what device your input/output is mapped to? On a Vista PC you can go Control Panel, Sounds (I think XP is set up the same) and it will provide you with the place to change how input and output is mapped. Please repost if that's not it...ed. -----Original Message----- From: j-say-bounce@xxxxxxxxxxxxx [mailto:j-say-bounce@xxxxxxxxxxxxx] On Behalf Of David Lepofsky Sent: Friday, October 31, 2008 11:49 AM To: j-say@xxxxxxxxxxxxx Subject: [j-say list] Head Set Problem I use the Logitech ClearChat Pro USB Headset It is a USB device. When I plug it in, I lose any control over setting volume. The computer's volume button makes no difference. The headset's volume button doesn't alter the volume. I plugged this same headset into another computer and these all worked fine. There must be some weird setting in my computer that is causing this, but I cannot find it. This happens whether or not I load Dragon. Also, with other headsets, if I unplug them, the sound routes back to my external speaker. If I unplug these, the computer goes silent and I have to re-boot. One more weird clue. When I plug in these headphones, the audio for jaws comes through the headphone, but the audio for sound effects from Dragon or Windows still come out of the computer's external speaker. If I adjust the computer volume dial, it varies the volume on the external speaker, but makes no difference on the headphones volume. Any ideas?
