HDA NVidia audio drops intermittently on HDMI

Hey folks,

I bought a new laptop and threw Arch into it. Ever since, I've been facing major audio issues, like the audio output shown as "DummyOutuput" even with the sof-firmware, linux-firmware and alsa-ucm-conf installed.

But now, with an external monitor through HDMI, I see that the audio cuts off intermittently. I'm not sure if the problem is related to GNOME in anyway as I see that, when I open GNOME settings from the top-right, the cursor lags for a split-second and at this point, the HDMI audio is cut-off for 3-4 seconds. It happens almost every time I open GNOME settings and even other applications. Sometimes I see it even while browsing on Chrome.

I installed the NVidia drivers through pacman and here's what I have,

$ sudo pacman -Qs nvidia

local/egl-wayland 1:1.1.7-1
    EGLStream-based Wayland external platform
local/libvdpau 1.4-1
    Nvidia VDPAU library
local/nvidia 470.74-5
    NVIDIA drivers for linux
local/nvidia-utils 470.74-1
    NVIDIA drivers utilities

The PC is an Alienware M15 R6 on which, I understand, the HDMI port is wired to the dGPU (i.e. the NVidia card) and hence, only when optimus-manager is switched to the NVidia card, I have video / audio output on my external monitor. Optimus is set to NVidia as seen here:

$ optimus-manager --status

Optimus Manager (Client) version 1.4

Current GPU mode : nvidia
GPU mode requested for next login : no change
GPU at startup : auto
Temporary config path: no

I have video and audio on HDMI but the audio breaks off intermittently as explained above.

Some other logs are as follows:

Re: HDA NVidia audio drops intermittently on HDMI

I've had related trouble I can't find a fix for, with audio dropping from TV plugged into HDMI. Particularly, audio that is fairly quiet, or devoid of human speech, will start cutting out intermittently. Interested in seeing how this turned out, as I suspect the fixes to be similar.
