Upgrading the linux graphics driver from 440.36-5 to 440.44-2 has caused extremely noisy audio via the HDMI port on my GTX 660 Ti graphics card

Motherboard: ASRock Z77 Extreme4
GPU: NVIDIA Corporation GK104 [GeForce GTX 660 Ti]
CPU: Intel© Core™ i7-3770K CPU @ 3.50GHz × 4

These are the updates I performed on RebornOS that resulted in extremely noisy audio via the HDMI port on my GTX 660 Ti graphics card:

I’ve verified that the hardware isn’t broken by playing sound via HDMI from an earlier version of the RebornOS live iso.
Audio from my 3.5 mm jack headphones is working correctly both before and after the updates.
Also trying linux-zen 5.4.3.zen1-1 kernel and installing nvidia-dkms 440.44-2 didn’t resolve the issue.

I’m having the same issue on a 980 TI. I originally thought it was a kernel update but both my custom and stock kernels have static unusable audio.

Here’s some more output:

I ran into this too, but I don’t think it has anything to do with the nvidia driver. I found the kernel change that triggers it, and it triggers for me for both 440.36 and 440.44.

Yup, you’re right. I applied the patch from Takashi Iwai to the 5.3 and 5.4 master branches of zen-kernel. The latest Liquorix kernel includes this regression fix and I can confirm it fixes corrupted audio with nvidia hdmi.
