P35-DS3R rev 1 MB with F13 BIOS\n\nrecently I installed Windows 7.\nI could not get the HD audio to work properly.\nWhen I plugged in the HS to the front panel jack I no longer received\na prompted asking what I had plugged in. I also did not get any sound\nfrom the HS. It still came thru the speakers.\n\nI tried everything. Seems others are having issues with this on other\nMBs, though not exactly the same problem, so I assumed it was a driver\nissue.\n\nWell, I tried ALL the drivers I could find. Then I discovered that if\nI plug the HS into the MIKE jack, I get a prompt and if I select HS\nthe sound is directed to the HS instead of the speakers, like it once\nwas.\n\nA new driver 2.31 just released. No help.\nI went back to XP and tried the latest driver. Same thing.\nI went back to the original Gigabyte driver disk and it still acts the\nsame way.\n\nI ohmed out the wiring and it "appears" to be OK.\nI checked out the solders on the IO board. Everything OK.\n\nThe only thing I haven't ripped out is the MB.\n\nHas anybody got any suggestions?????????????
