Solved IDT High Def Audio, buzzing sound when playing any sort of audio.

Hello,


Starting about a week ago whenever any audio is being played through my computer (speaker or headphone) I will hear a buzzing sound and occasionally the audio with skip. This happens weather I am playing audio that is being streamed from the internet or that is on my computer directly.

I have tried several things to fix this problem including installing all windows updates that are available as well as updating my audio drivers.

I am running windows 7 home premium 64 bit. My computer model is hp pavilion dv7t quad 6100 and I have IDT high definition audio codec driver version 6.10.6381.0 which my computer says is the latest driver version. Updating to this version has not solved the problem, however.

Any help with this problem would be greatly appreciated. If there is additional info that is neccesary, please let me know and I will post it.

Unplug the speakers from the PC and see if you still get the buzz with headphones. Some "buzz" problems can be related to "AC power ground loop" problems if some separately powered devices are connected.

Noise and skipping are problems that have been posted here before. There is no "one fix" for that. There are possible hardware problems, drivers (including video drivers), Interrupt issues, Wi Fi caused, etc.

Skipping can be because the other device that is on the shared Interrupt that the sound is on is interrupting the sound. Sound is always on a shared interrupt (IRQ) with a higher priority device. You can try this: go to the Device Manager, RIGHT click on the entry for the IDT and then LEFT click "Uninstall". DO NOT check the box to uninstall the drivers. Then restart the PC and when Windows starts it will detect the sound and reinstall it and some times put it on a different shared IRQ.

Uninstalling the device and restarting the computer seems to have fixed the problem! Thank you so much!

Great. Glad you got it fixed and thanks for the feedback.

Firebird, wanted to know I was having this problem in 2018 and your idea worked! Thank you
