hp laptop audio and video problems (unless connected through hdmi)

[Badger187]

Problem started a little over a month ago on my HP laptop running Windows 7 64bit.

When I connect the laptop to my either of my TVs through an hdmi cord everything works fine. Videos run smoothly and the audio is in sync as if there's no problem.

If I try to watch a video on just the laptop though the problems start. If I try to play anything (songs/videos) in Windows Media Player then it says "Windows media player encountered a problem while playing this file".

When I play a video on YouTube the video runs smoothly but there isn't any audio to go with it.

If I go to control panel - sound - speakers and headphone properties and try to play a test sound it says 'failed to play test tone'

Attempted to update the IDT High Definition Audio CODEC driver but windows said it was up to date. Same thing with the Intel(R) Display Audio driver.

Thanks for any help

Are you leaving the HDMI cable connected to the PC when you try to us the PC's sound (IDT)? Generally, when an HDMI cable is plugged in and detected the sound automatically switches from the "Speakers" (the IDT) to HDMI as the default audio playback device and thus no regular PC sound.

No, all of these problems are occurring with the HDMI cable unplugged. Nothing else is connected to the laptop.

Check the Default Playback Device in the Control Panel/Hardware and Sound and finally the Sound panel. Your "Speakers" (PC sound) should be set as the Default Playback device. If its not switching back, from HDMI, when you unplug the HDMI cable that could be an issue.

If not sorted out yet, some hints that may be useful. Try reinstalling HP's own drivers for your specific model, download from HP support and save them.

Create a manual system restore point (or even better, a disc image).

If relevant, temporarily stop windows from automatically trying to install drivers, see Automatically get recommended drivers and updates for your hardware.

Go to Device Manager and uninstall the old audio\video drivers. Restart.

Install the downloaded HP drivers. Restart.

This will ensure your HP gets back to stock in the dept. where you've got trouble, then see how things work out and do any eventual further troubleshooting from there.

I had checked that and it wasn't the problem.

Uninstalled the drivers but forgot to turn off the automatic install however after the auto install finished and i restarted the problem had resolved itself.

Thanks for the suggestions and help everyone!
