Hello guy, I took my laptop to the technician and they open up my laptop and running the test and discovered that my laptop soundcard is not damage but the wire may be loosed so they tighten it up, to my amazed it work again but to find that the speaker onboard is working but not for the sockets (both mic and headphone), technician tried again but to the same result. (they literally shook their head) I took it home and reinstalled from Vista to XP pro hope it just a software conflict or whatever and then it work (both sockets and laptop speaker) but only for a short time cuz if I restart it, the sound just disappear again. My head is completely numb now cuz I can't think of how to fix this stupid laptop's sound of mine. Also I am curious why EVEREST displayed Intel 82801GBM ICH7-M - High Definition Audio Controller on my laptop but instead it said I'm using Realtek HD Audio? is that the issue to my laptop's sound disappearing?
