Dear forum members,
i'm a Regular windows user since Windows XP SP2. few months ago i upgrade to Windows 7 ultimate (32 bit). i have onboard sigmatel sound card which works under Windows XP SP2/SP3 without any issue after installing sigmatel audio driver for Windows XP. but it's not working under win 7
i tried to install that XP driver under windows 7 with 'windows XP SP2' compability mode. it installs well, but no sound except some heavy noise from speaker when i play any kind of music, video etc.. I use a Microlab 2:1 speaker.
i also tried Win Vista driver for sigmatel high definition audio codec, but same issue happens again. that means, no sound except heavy noise from speaker.
built-in audio driver (high definition audio codec) working good under Windows 7. but there is also an issue with it as well. i can play sound nicely with this driver when i connect my audio jack with front panel. but no sound when i connect it with Rear panel.
that means, i only listen clear sound with this driver when i use front panel, but not Rear panel
but in Windows XP i can listen sound from both front & rear panel, but under windows 7 (with default/built-in audio driver) only front panel working, not rear panel.
so everytime i want to listen music or watch video i need to disconnect my audio jack from rear panel & connect it with front panel to hear sound. it's a very annoying work.
i search online many times to find a solve for this problem but no luck
recently i heard about this forum & decide to give a post here about my problem.
i think if anyhow i find an audio driver for my sigmatel which will work under my windows 7 ultimate flawlessly i can hear sound from rear panel as well.
this problem is making me crazy......
is there any solution of my problem? plz guys help me!
