I have read about this happening a few times but none of the threads seem to have helped. I have an HP m7170n desktop and I installed Win 7 32-bit. When I run device manager on the PC it shows two errors under other devices, one "ethernet controller" and the other "multimedia video controller". I am assuming these have nothing to do with the sound, but then again - I am a noob when it comes to the guts of my PC.... under sound, video and game controllers it shows "high definition audio device" but there is no error, shouldn't this mean I should have sound? I am not too sure what brand my sound card is so I downloaded Belarc Advisor to see if I could find my device type and it only says high definition audio device... would there be a universal driver software I can download? Or does this PC type have a brand name audio device that just isn't showing? I'm thinking maybe it only says that because I haven't installed a driver for it, yet?
