Audio driver is "VIA HD Audio Deck" ,driver version 6.0.1.7600 ,codec version VT1708S, pakage version 7.6.00.31 .When I use windows7 (64-bit) my front panel microphone does not work.Computer cannot detect the jack.Front panel headphone works but sometimes some noise appears.I want smooth playback.But when I use windows XP microphone and headphone both work properly.How can I solve this problem?
