Fix Nvidia RTX 30 Series HDMI HD Audio Drop Out

I’ve written several articles about my recent foray into laptop gaming. I purchased an ASUS TUF gaming laptop, Logitech Keyboard and Mouse, and Logitech Headphones to use with my big screen in the living room. Everything has been working well until a week or so ago.

I noticed that when my laptop was connected to my home theatre system via the HDMI port, audio would drop out for 1 or 2 seconds every minute or so. It happened in games, movies, YouTube, and everything else. It was slowly driving me insane.

I tried every possible setting and trick I knew of to fix it. I swapped out cables and changed the Nvidia HD Audio driver to the standard Windows driver, I adjusted from various versions of surround sound to stereo. I even switched to the TV’s internal speakers. Nothing worked. I strongly suspected it was a driver problem because my headset and laptop speakers worked fine. The issue only occurred when using the HDMI port but video through it was great.

Today I installed the previous Nvidia driver package (466.27) and the problem is fixed. Once I corrected the problem and understood the cause, I was able to find a thread on Nvidia’s forum where other people are having the same issue with the 466.47 driver. That forum is at Stuttering sound driver 466.47 | NVIDIA GeForce Forums. You can download the 466.27 version of Nvidia’s driver from NVIDIA DRIVERS GeForce Game Ready Driver WHQL, just run the file and it will remove the new version automatically.


  1. Kevin, if I wasn’t a guy, I think I’d want to have your babies. I reset Windows 11, then dropped it completely for Windows 10, then back to 11, updated my bios firmware, receiver firmware – been pulling my hair out.
    This seems to have fixed it. Oh my. This is a brand new gaming rig and i was about ready to drop it back off at the store I bought it from.


  2. Since changing monitors from a Samsung 27″ to an Acer 32″, I’ve experienced audio drop outs using the display port and audio out port on the Acer monitor. I have an RTX3070. Every few minutes, 1-3 seconds duration, audio deadens. Tried the Nvidia setting, power management set to max performance but didn’t work. I installed the Nvidia driver 466.27 from 516.94 and for the last two days haven’t noticed any drop-outs. Some incompatibility between the video card, display port, driver, and monitor’s audio block. Works now. Thanks for the post!
