Hi there!
I have this one setup: [HTPC] --HDMI--> [TV (LG)] --OpticalCable--> [5.1 Sound System]
And I want to have 5.1 sound when I use any application (now I use Kodi, Steam and Retroarch).
On the HTPC side I have pipewire, pipewire-alsa, pipewire-pulse and wireplumber.
I didn't do any specific configurations, just selected the "Digital Surround 5.1 HDMI" profile in the pavucontrol and played a bit with enabled codecs (i am unsure what this setting actually changes).
TV configuration:
DTV Audio Setting: MPEG, Dolby Digital, Dolby Digital Plus, HE-AAC, Auto
HDMI Input Audio Format: Bitstream, PCM
Digital Sound Output: PCM, Auto, Pass Through
Now when I run `speaker-test -t wav -c 5 -l 2`, I hear only "Front Left" and "Front Right" sounds. So, i need to configure sound properly.
As I understand, HDMI is able to carry audio signal in different formats.
Is it possible to get supported formats on the HTPC side?
I tried to use the read-edid, but didn't get anything related to audio capabilities.
How to configure output HDMI audio format with pipewire?
I see some variants in the pavucontrol (AC3, EAC3, DTS, ...), but it allows me to set multiple options. Unfortunately the pavucontrol doesn't have any documentation.
My current configurations:

I "downgraded" my setup from pipewire to pulseaudio, because kodi doesn't work well with it. But i think that following ALSA configuration should work with pipewire as well.
I created ~/.asoundrc with this content (found here):
pcm.a52 {
slavepcm "hdmi"
}After restarting pulseaudio I selected in the pavucontrol the new configuration profile "Digital Surround 5.1 (IEC958/AC3)" that encodes the output sound as AC3.
The audio configuration is still unclear for me and I am unsure if it is a proper solution, but at least it works. So I mark the thread as [SOLVED].
