today (2020-12-07) an upgrade of PulseAudio was released that fixed the issue for me.
pulseaudio-utils (12.2-4+deb10u1+rpi2) pulseaudio-module-bluetooth (12.2-4+deb10u1+rpi2) pulseaudio (12.2-4+deb10u1+rpi2)
Yup, that update was to fix that issue.

But in original raspberry lite this block uncommented. Why we have the issue?

Hi!
By default, PulseAudio on the PI4 treats all analog outputs as Mono, including all HDMI outputs. I was able to track down the issue and discovered it is simply a configuration file issue that has been fixed upstream two years ago.
The PulseAudio version included in the Pi OS is a bit old, but I was able confirm that simply updating the configuration file without upgrading the PulseAudio version will address the problem.
In
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf
, simply comment out theanalog-mono
section. This will allow the existingstereo-fallback
section to take over.Comment out this section:
I think including this simple change would make a lot of people using their RPi as a workstation connected to an HDMI monitor happy!
Before the change:
Notice how both PulseAudio sinks (headphones and HDMI1) are configured as Mono outputs:
After making the change and running
pulseaudio -k
