I'm not new to the penguin. The penguin and I go back more than a decade. That said, I also don't think I'm a greybeard by any stretch of the imagination.
I'm hoping to attact "bodacious penguins". Those that wouldn't mind addressing Linux issues, Linux-based surround system issues (uh huh- I'm willing to bet the firmware on a majority of A/V Receivers is Linux), and general computing issues.
It's a long one, but I want you to have too much information, than too little. I respect your time!
I am a musician. I make music. I use a Behringer USB DAC for my studio-side of things.
I am a music enthusiast. I listen to lots of music. I play my playlists through VLC and occassionally Clementine.
The Behringer DAC has a nice set of studio-quality headphones jacked in.
The PC we're talking about is cabled via HDMI to the TV. The HDMI port on the TV that the PC uses is HDMI1.
The signal chain for is as follows:
HDMI_cable_a goes from PC's GFX (Graphics) --> Panny A/V 5.1 Receiver on jack "BD/DVD Player IN".
HDMI_cable_b goes from Panny A/V 5.1 Receiver on jack "Out" --> TV (HDMI1 port on the back of the TV). So, we have 2x "good quality, but absolutely not the best quality" HDMI cables in this setup.
I have, indeed, a 5.1 surround sound system. It worked fine with Deb12LTS until a few weeks ago. Then, with all the issues and strange happenings with my Debian12 system (the one we're talking about), I decided it was time to wipe everything, and give btrfs subvolumes a try, in a multi-boot system. That was last Sunday. Welp... I can't even get things right with Debian12, so I haven't gone further with the multi-boot.
And now that we have this all established... I'd like to give you the punk quote of the day: "Punk's not dead, it just deserves to die when it becomes another stale cartoon." -Jello Biafra, Dead Kennedys "Chicken___t Conformist" from their Bedtime for Democracy album.
Now we're jamming. Hotay, here we go. \m/
The issues with my Debian 12 PC + Surround System + DAC + Music Apps
I present to you Mone Risa. She's my cruel mistress. New PC build. Did it all myself, thank you very much. I know my way around computers. That's all I'll say.

I'm not going to bore you on old issues. I'm going to bore you on the issues at present.
- My Debian 12 behaves as if my LS (Left Surround) and RS (Right Surround) speakers, behind me, are just L and R speakers. The 5.1 setup is broken.
So, for example, when you go to Debian Settings --> Sound --> Output section: HDMI GM206 High Def Audio Controller --> Configuration: Digital Surround 5.1 (HDMI) Output... and I click TEST...
"Rear Right" plays thorugh front R speaker. "Rear Left" plays through front L speaker. The cabling to and from the Panny A/V Receiver, the speakers, and the PC hasn't changed. Full stop.
- I know that Debian uses both ALSA and PulseAudio for sound controllers (did I say that term right?). Which device uses which sound controller (PulseAudio/ALSA) I'm still trying to figure out. How can I generate a list of programs that use X, and a list of programs that use Y (X=ALSA Y=PulseAudio)?
Here's the output of pactl list: https://flic.kr/p/2p4yYBb
- Clementine doesn't play through anything. No ideer what's up on this fresh installation.

2) aplay: https://flic.kr/p/2p4sf5s
Now. If you'd be so kind as to reference what you'd like to help me out with so that I know which exact issue we're addressing... I'd be happily punk in drublic. THANKS IN ADVANCE, and I'm quite pleased with how my first post went! I'm humble in my knowledge of Linux and its quirks err... features! I am a Debian person. Love me .deb files, can't get enough of 'em.
Thank you for your time, and thank you for your pearls of wisdom. Some day, I want to grow up to be just like you, and help others out... because the Linux community is magnifique. Adieu! C'iao! Auf Wiedersehen! Tot zo! Oh... "Should I stay or should I go now?" - The Clash
******** UPDATE before POSTING ********
Had some VLC issues not playing through the Panny A/V surround system. VLC is using something I'm not all too familiar with, but can certainly research further: PipeWire Media Server. ALSA.
So VLC is now happily playing through my broken 5.1 Panny surround system. One issue down! But the speakers (Rear Left + Rear Right) still are treated as Front Left + Front Right)
