This isn't the first time this has happened and usually I just reboot the computer and the sound is back. This time I went to device manager and found: Microsoft Kernel Wave Audio Mixer Cannot load the device driver. May be corrupted or missing. Code 39. driver is kmixer.sys I can reboot and this will clear itself up, but has anyone else had this problem and what did they do to fix it?? Thanks for any replies.

Computer info: XP SP2 Pro 2.13G 512 Ram Trying to install: Twinhan DTV ATSC D&A model 32500, PCI card I've tried their website -0- I've tried moving it from PCI slot to another PCI slot -0- I've tried installing new hardware -0- When I use the disc for installation that came with the card, I get an error message "No supported device found! Attach the device & press "Yes" to try again or "No" to continue...." ..... so I press no to continue, then when I start the program Twinhan DTV I get another error message "Cannot support the card or driver, please check the hardware installation." I could really use some help. How do you get a computer to see a new piece of hardware that you have put into it ?????????? Please ... someone surely has had this happen to them before.
