I have the same issue. I notice that in addition to the sound being extremely distorted and scratchy, the volume slider in pavucontrol doesn't work. The problem appears both with pulseaudio and alsa.

Downgrading also solves the issue for me. linux-5.4.2.arch1-1 with nvidia-440.44-1 works too.

I can confirm that this also happened to me, thought it was a pulseaudio issue, but downgrading pulseaudio did not help. So, the problem must be related with the nvidia driver.

Edit: I am using gnome btw, GTX 1060 nvidia 440.44-2

Confirmed with GTX 1080 and Linux 5.4.3 with nvidia-dkms 440.44-2 driver.

confirmed with GTX 660 and linux-5.4.3 + nvidia 440.44-2 - extremely distorted signal.
The fix in kernel https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=6fd739c04ffd877641b01371f9fde67901e7f9cb
worked for me.

I can confirm audio issues also, with the following: Kernel 5.4.3-arch1-1; nvidia 440.44-2; GTX 1060 audio via HDMI.

Booting with linux-lts (4.19.89-1-lts) with nvidia-dkms 440.44-2 resolves the audio issues for now. I'll keep an eye out for new arch kernel release.

Thanks
Samuel.

Mine results (RTX 2080 TI):

* linux-5.4.3.arch1-1 nvidia-440.44-2: sound distorted.
* linux-5.4.3.arch1-1 nvidia-440.44-1: nvidia-modprobe cannot load module, gnome tries to start with wayland and fails.
* linux-5.4.2.arch1-1 nvidia-440.44-1: Everything works fine.

Well, that's weird. Does anyone know whether this is tracked either in the nvidia forums or on kernel bugzilla somewhere?

https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=6fd739c04ffd877641b01371f9fde67901e7f9cb worked for me as well (GTX980M). Is this something that can be backported to this package?
Comment by Sven-Hendrik Haase (Svenstaro) - Tuesday, 17 December 2019, 11:06 GMT
So then this is actually a kernel issue?
Comment by Frederick Zhang (FrederickZh) - Tuesday, 17 December 2019, 11:15 GMT
I think so. Applying the mentioned patch was the only thing I needed to do to fix it.
Comment by Ringo Starr (kanto) - Tuesday, 17 December 2019, 11:30 GMT
How do you apply the patch?

IIRC it was:

Can you confirm the issue is fixed in linux 5.4.4.arch1-1?
Comment by Andrew Rabert (Draje) - Wednesday, 18 December 2019, 01:56 GMT
Working fine for me in 5.4.4 (980 Ti).
