That "prblem" may be related to the broken pin.since my computer still works but got problems
Well if it was 4 sections there is a chance it could be semi grounding out because the one on the motherboard only supports 3. I’d look into getting a usb sound card or maybe a pci soundblaster card depending on your budget. Could also get usb headphonesit can't be related to the headphones since the sound follows with the crunch it has to be hardware related
Except you still got that crunchy computer...well iff its not related to dirty cpu pins i can consider this solved
