I have a Toshiba P200-1ED laptop, and in the last 30 minutes, I've got a problem I've never had before.

Trying to record a phonecall to the hard drive, I set the recording program to stereo mix and plugged the phone reciever into an adapter I bought. I tried the adapter into a tape player first, and it worked (and still continues to) with that.

However, it wouldn't record on my pc and gave alot of feedback, so when I took it out, it problem started. The built in speakers started making a "bumb bumb bumb" feedback sort of sound. I tried putting headphones in and it happened through them too. I restarted the pc twice, and its still happening (although since I restarted it, the built in speakers doesn't make the sound anymore, it just stays silent.) When i plug headphones into any of the 4 sockets it just constantly goes "bumb bumb bumb".

I've reinstalled the drivers from microsoft and it still happens. Whilst applications such as itunes and Adobe Audtion plays any music and the dB meter goes as normal, the speakers stay silent and headphones keep with the feedback.

So is my internal sound card broke, and if so, can it be fixed?

Thanks
