T60 Sound card died (probably)

[WiSaGaN]

After an accidental water split near the earphone output on my T60, the sound gradually died in several seconds.
Now the problem is the earphone output and the speakers don't work any more. But in device manager and all the other software side the sound card is there and "work properly".
Is there something I can do about it?
Now I am using a 5 $ USB sound card output, but as you know, it just produces "sound" and not enjoyable at all.
Thank you for your help in advance.

Echo Indigo IO/DJ could be a very nice choice for you if you don't mind a prominent butt by the left palm rest.
