This is getting embarassing. I know it doesn't seem like it but I have\nbuilt every PC since I bought an 8088 machine back in the 80s and I've never\nhad this much trouble. I probably should have just stuck with the 8KHA+.\n\nAnyway, I've got no sound from my 8RDA3+. The nVidia sound drivers are\ninstalled and I "see" activity on the nVidia mixer but nothing out of the\nspeakers. Speakers are good because I just played something on my laptop to\nverify. Everything in the device manager shows as working but no sound from\nany audio source, the web, Winamp, or a CD. Went through the XP\ntroubleshooter and everything is set up correctly.\n\nThe sound on my 8RDA+ works and I see that it shows two nVidia devices; the\nnForce audio codec interface and the nForce MCP audio processing unit. For\nsome reason, the latter did not load when I installed the nVidia audio\ndrivers. I will try the installation again but if you've got any other\nideas, I'm all ears!\n\nThanks.
