Pavilion dv6 3016sl - No audio after updating to windows 10

[Alomor]

Hi, after the upgrade to windows 10 my laptop has no audio at all. I tried installing every IDT driver that I've found (windows 7, 8, 8.1 - apparently the windows 10 drivers doesn't exist) but none of them worked. I tried to uninstall the IDT device in Device management and let windows automatically reinstall the drivers, it didn't work. I tried the troubleshooting with HP assistant and the windows 10 built-in troubleshooting but none of them worked. In the IDT app and in the audio settings of windows everything seems fine but I get no sound at all. Please let me know if there is any fix for this. Thank you.

Hi:

There is one actual W10 IDT notebook audio driver and that is this one.

I don't know if it will work for your model, but it does work on several others.

I had already tried that version, but the installation fails (says the hardware is not compatible with this version)

There is only one other thing that I know of you can try if you have not done so already, and that is this...

Go to the device manager and click to expand the Sound, video and game controllers device category.

1. Select the IDT High Definition Audio CODEC under that category.
2. Select Driver tab.
3. Click the Update Driver button.
4. Select -> Browse my computer for driver software.
5. Select -> Let me pick from a list of device drivers on my computer.
6. Select High Definition Audio Device (Not IDT High Def... this is important.) and click Next.
A warning message may appear, but click Yes.
7. Windows has successfully updated your driver software.
8. Restart the PC.
The key is step 6.

Unfortunately, that didn't work. I tried all the drivers versions I could find and none of them work. I guess I have to roll back to windows 7.

[Paul_Tikkanen]

Sorry that didn't work for you.

Yes, you will have to go back to whatever OS you had where the sound still works.

[Alomor]

I rolled back to windows 7 home, the same version as the original (where the sound worked), but I still get no sound, no matter if i use High Definition Audio Device or  IDT High Definition Audio CODEC (downloaded from the HP website).  Unfortunately I cannot use the recovery partition to restore the notebook to factory because the hard disk was changed with an ssd. Everything else is working, I really can't explain it. If you have other solution please let me know.

[Paul_Tikkanen]

To rule out the audio chip failed, if you still have the mechanical hard drive you removed, install that back in the notebook and see if the sound works again.

Other than that, I have no other ideas for you to try.

[Alomor]

Unfortunately I don't have the old hard drive. I've ordered a pair of new speakers but they will take 2-4 weeks to arrive. It seems nearly impossible to me that both speakers are broken, but the fact that the headphone jack is working correctly give me hope since theoretically the audio chip is still working. 

[Alomor]

The new speakers are working well, with both Windows and IDT drivers. The old speakers were broken.
