I just got a new SB Audigy card for my carputer and everything works like it did with my on-board sound card except the HD Radio. I'm running it into the mic/aux/line-in jack. When I first start the HD radio, it plays fine, but as soon as I touch any of the volume buttons, it mutes and won't come back on unless I exit RR, open the Audigy control panel and unmute the line-in jack. I've tried changing the Radio settings in RR to unmute the line-in, mic, aux all with no success. I've tried the Line-in command with no success. I've tried checking the box to reset the soundcard with no sucess. No matter what I do, as soon as I press volume up, down, or mute and unmute, everything shuts off the jack. Also, if I don't use RR and just use the HD software to control the HD radio, it seems to work fine, but of course I'm controlling the volume through the Sudigy directly at this point. All my other stuff plays fine...mp3's, movies, etc. Any ideas?
I found in some other posts about other cards that the winamp line-in plug in worked. It did solve the problem.
