Bleh. This's been gnawing at me for a while. Namely, something funky with the driver is causing a loud background squealing generated by the microphone output. (Not the microphone, I was able to confirm this much.)
Edit: Clarification: The squealing is transmitted over any sort of voice chat program or sound recording, not coming from the PC itself.
I'd like to fix it, but at this point I'm starting to run out of ideas. If anybody knows any solutions, I'm running an HP a1510n, sound card apparently being Realtek HD Audio or something similar.
If anybody needs any more details, page me or reply to this with what manner of detail(s) you need and I'll try to get them in as quickly as possible.
Any help is much appreciated!
Edit: Changed the topic name to something a bit more relevant.
