Camilla Mo, in Driver Error
  1. camilla mo THANK YOU THANK YOU THANK YOU!! I was so frustrated. I tried many solutions given online nothing worked!!! The solution given by you WORKED!!! it just made my day! Thank you once again.

  2. Thank you very much. I wasted whole day just to get this done. I was almost ready to throw away my sound card, thinking my sound card is dead. But I came to your site. So lucky I was!!! It worked right away after I did what you recommended. Thanks again. I don’t know why windows 10 make things so complicated and hard. I was much better with my earlier versions of windows.

      1. Great job Camilla Mo, thank you. Windows 10 Creators Update downloaded 17th April 2017 messed up my system and stole the codec.
        After a couple of failed attempts I went back to the “good old days” and restarted my system after reloading the codec.
        My 5.1 Surround Sound system is now working again.
        HP and Microsoft could not solve the problem but you did.
        You should be working for them at a VERY LARGE salary !
        They should both get their act together and give real support for their customers.
        I might now investigate “Driver Easy” if you have anything to do with it.
        Thanks again and have a good day.

  3. Thank you! I have had issues with my sound for a couple days now. It happened a few weeks ago too. I went back to the last update and it fixed it the last time but not this time. So glad you shared how to fix this. I really appreciate it. Thank you once again.

  4. Yay- after hours and disappointment I finally got it back because of these instructions. I even restored my computer to factory settings (What a headache)- thinking it would come back.. NOPE it did not… Went to bed and got up this morning with a clear mind – found this and BAM got it! THANK YOU

  5. It fixed the problem with solution 1. The icon of the sound no longer has the red cross. However, the sound does not work with the system speakers in the laptop. I tried solution no. 2 and I got the same results( no sound with speakers and sound with headphones)…something interesting is that the sound when using the headphones, works however, it is very low and when I turn the volume up, it echoes just when a microphone sound is turned up over the limit….

  6. My speakers stopped working after I had to reset my PC. I spent 2.5 hrs trying to fix the speaker issue. This solved my problem. THANKS!!!

  7. Thank you so much!,this is the definitive solution to so much problems with IDT High Definition Audio Codec,I am greatly indebted to you.

  8. thank you sooooooo much, it actually worked! i had to reset my computer due to the kids stuffing it up, i have a powerpoint assignment due next week, where i need sound, your advice worked so easily! ive been at this computer for 24 hrs trying everything, thankyou thankyou!!!!!! you saved me BIG TIME

  9. THANK YOU THANK YOU THANK YOU THANK YOU THANK YOUTHANK YOU THANKYOU THANK YOU THANK YOU THANKYOU! THANK YOU VERY MUCH! THANK YOU SO VERY MUCH! THANK YOU SO MUCH SOOOO MUCH THANK YOU!!!!! I hope anyone involved with this site has an awesome day- EVERY day and FOREVER!

  10. Whao! This is brilliant. How I wished I had seen your posts since this issue started about 7 months ago. Now working perfectly after trying the first “help” or solution method. Thank you so much.

  11. From what i’v seen, every post has no sound, can’t install, failed update and so on. Well i have sound but still can’t get it to update, should i to it or just leave it as it is?
