Sounds liek tehre is a problem with you case front panel audio. it could be ac97.....not compatible with HD audio connector onn teh motherboard.....
No, I resolved the issue. The issue seems to be no where related to mother board or drivers its only the configuration. I configured the HDMI graphics properties and once I configured the graphics card all seems to be fine. So does that mean that video graphics has to be configured to get the HD audio?
