I have read as many posts as I could find that seem to relate to my problem, even asked ChatGPT, all without success. I am not new to Linux but this is the first time I am trying to do something I guess would be considered custom with audio. I have never had to play around with it before, the defaults just worked. The configuration and learning for audio has been more difficult than I expected though. Here is my problem...
I have an ASUS motherboard with a Soundblaster audio card installed. The motherboard has audio hardware. I intend to use the Soundblaster for HAM radio audio connections and the motherboard audio hardware for regular audio functions. After installing Debian 12.9 and Cinnamon the audio works from the Soundblaster as the default but I would like to change that to the motherboard's Intel PCH audio. I have seen posts that describe how to do this, but none of them has worked for me because the other devices are not listed where I need to change them, or if they are, changing them doesn't work. Some details...
This shows the default, as installed Soundblaster, that works currently and only that one sink is listed by pactl.
$ pactl list short sinks
Code:
122alsa_output.pci-0000_08_00.0.analog-stereoPipeWires16le 2ch 48000HzRUNNING
This shows the full list of ALSA playback devices. I am trying to change the default to the HDA Intel PCH analog device. Card 2 is what the system defaulted to (as installed) and I can't figure out how to use card 0.
$ aplay -l
Code:

In the GUI when I go to sound settings, the screenshot shows my only two options (Soundblaster digital or analog output) with the Soundblaster analog output selected and working. No options for card 0 that are present in the ALSA devices listing:
When I run the alsamixer it shows me all three cards but when I use F6 and select card 0 it does not actually change the output. It keeps card 2 as the output default.

Further details for my system are:
Linux 6.1.0-31-amd64
#1 SMP PREEMPT_DYNAMIC Debian 6.1.128-1 (2025-02-07) x86_64 GNU/Linux
Description:Debian GNU/Linux 12 (bookworm)
Release:12
Codename:bookworm
debian_version: 12.9
I read in a post somewhere that timidity can cause problems and I verified I do not have that installed.
In my extensive debugging attempts, I do have both pulseaudio and pipewire installed. I have tried so many things I'm not sure, but I think pipewire was installed by default and I added pulseaudio to try to get the other audio outputs to work based on reading posts in the forums.
