New rig with GA-h55m-usb3 mobo with Win 7/32 pro SP1 - back panel sound fine. but trying original front panel jacks (AC97), and Silverstone fp94s jacks (HD or AC97) nothing. HD recognition should be automatic! Audio is integrated on board Realtek, driver
I have upgraded the bios and the drivers
. I have tried changing the switch to turn off automatic recognition for AC97. I can see that the system playing, I have ensured the voilume is up. Tried different speakers.
Having read other forums, come to the conclusion that this is a win 7 issue, and/or a mobo issue (however I gather this happens on other mobos).
