I have HP Pavillion g7 Notebook PC - Suddenly my sound stop working. I only have sound when I put headphones and even then it's just when the headphone plug is inserted half the way. When i plug in headphones properly (fully plugged) sound is kind of scrambled. Without headphones I have sound for the first couple of seconds and then it goes mute. When I check volume control etc. appears as if it's ok.
Regards,
B

Hi,

Try the following.

Download the IDT Audio installer on the link below and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55082.exe

When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and start the notebook.

Let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

If you still have no audio, open windows Control Panel, open Administrative Tools and open Services. Check that the following services are all showing as Status= Started and Start-up Type= Automatic

Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder

If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type', select Automatic and click Apply to save the change. Then click the Start button.

Hey,

I have the same notebook, which is just under a month old. My problem has been that the sound is very inconsistent in different programs and w/ or w/o headphones and it's pretty annoying.

What I mean is, I have my headphones plugged in, and the sound comes out the headphones in iTunes, but comes out the speakers in Firefox. Or vice versa, it's weird. Then I have a Native Instruments music controller hooked up, which when that program is open and hardware on...sometimes the sound plays through the headphones, sometimes through the speakers, and a few times there was no sound at all.

I followed the above instructions, and it did fix a minor issue that has happened randomly, which was the scrambling issue that Branko is having.

But still, my music program goes through headphones and Firefox through speakers as I type this. I just want everything to come through the headphones when plugged in, and the speakers when not...lol...

Ok, here's what has happened - I do the uninstall and the tickbox gives me the option to delete the driver software which I do check. However, when I restarts computer in the order as explained, shut down notebook, adapter, battery etc... it automatically installs my audio device - the old one I guess. Now even my headphones don't work. I don't know if it finds it on the internet or i still have software on my comp.
Please help

Hi,

After uninstalling the current IDT driver, after you restarted your notebook, did you run the IDT Audio installer that you downloaded at the start of the procedure?

Regards,

Yes, I did and as an administrator. But when I installed it it has a "!" symbol next to the installed sofware. Unable to start it. Followed your procedure to the letter.

Hi,

Try the following and let me know.

Open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - do not select to delete the driver this time.

When this has completed, restart the notebook and let Windows fully load.

Once again, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Properties - is there an error code shown and if there is, what is it?
