I am running it on a NUC10, never needed to try it on a Pi, and with the mini HDMI outputs it is always a pain. I do have 6 about, but all permanently running Ropieee or RooExtend
Regards
Mike
Iâm on a NUC11, seems like I remember seeing some issue with the HDMI audio on the 11 or 12 when they first came out?
There were issues with Roon Rock as it didnât support the chipset, but I donât remember there being an issue with DietPi, but I have only been running it for the last year so do not want to claim any kind of expert status. It is something I use regularly with my setup, but i have never tried it with a Marantz system
Tried a new C2G âHDMI with Ethernet - 4K 60Hzâ cable and got the same results. Changed an HDMI input setting on the Marantz from âEnhancedâ to â8K Enhancedâ but no difference.
Very odd, I take it you have the intel HDMI driver installed?
Tried a fresh re-install of Diet-Pi with only (121) Roon Bridge installed, in case some how the Chromium display or Dashboard were causing some issue. Still get the same results.
Now reading the ALSA man pages, tried âspeaker-testâ but got the error âplayback open error: -2, No such file or directoryâ, Iâm assuming I donât have the syntax correct
Iâve tried it with and without the Intel drivers, same result.
Are you using HDMI 0 (audio settings Roon)?

Good call, Roon Bridge should expose more than one HDMI device HDMI 0 is the one to use.
Yes, using HDMI 0 in Roon, and it works when set to 2.0. It also works when Roon is set to 5.1 or 7.1 when I play a 2 channel track, it only fails when I send a multi-channel track when set to 5.1 or 7.1.
I set the default sound card in dietpi-config, and then was able to get speaker-test to work with -c2, -c6, and -c8, but Iâm unfortunately not at home to hear if it is actually passing through the Marantz receiver. Will report back this evening.
I confirmed speaker-test works with 2 (2.0), 6 (5.1) and 8 (7.1) channels. So it is not the HDMI port, not the HDMI cable, and not the Marantz receiver.
Seems the failure occurs somewhere between the Roon Bridge and ALSA.

Anyone have anything else to try?
Sorry out of options here itâs an odd one. @MichaIng any more advice for David?
Odd indeed, I just wanted to ask whether HDMI ports has been ruled out, but when speaker-test can do 7.1, then it is. Though, just to be very sure, do you have or can generate a little more complex 7.1 wav file that you can play with aplay?
As Roon uses the bare hardware device directly, and no ALSA plugin that could be configured, channel number enforced at ALSA end or any such, we seem to be a little out of options on the OS level software side.
What can be tried is a kernel upgrade to Linux 6.12 from backports:
apt install -t bookworm-backports linux-image-amd64
Can be done as well for the Intel firmware:
apt install -t bookworm-backports firmware-intel-sound

After installing the kernel and intel firmware speaker-test no longer works and no audio from Roon, not even 2 channel.

You did a reboot? What is the output of:
aplay -l
Uncommon that the Debian backports kernel has any issues 
.
Any kernel errors?
dmesg -l 0,1,2,3
Very surprising, and then I hope whatever the issue is, it is fixed until Debian Trixie is released, which is expected this summer. Freeze dates have been published already: Bits from the Release Team: trixie freeze dates
Since Linux 6.12 is the LTS, that wonât change anymore (only patch versions).
However, you can downgrade the kernel like this:
apt install -t bookworm linux-image-amd64
