It seems pulsaudio tooling is missing by default now in Trixie. I did fix it twice (remove pipewire and re-install native pulseaudio). i use networked pulseaudio and that does not work if emulated via pipewire.
You will see this on Pi4 RPiOS TrixieThis has been the case as long as I know. Audio on 3.5mm actually works fine, although not super high quality. RPi5 has no such modules anymore, maybe that is the reason it fails or is sort of forgotten to test, I don't know. I have other ARM computers with real dedicated Audio chip or on the SoC. Those need enabling via DTB and/or overlays. Then just standard audio tools to set what you want. CLI or GUI desktop traybar or so.
You can disable 3.5mm audio in config.txt, I would do that, but haven't done it yet although 3.5mm is unused for my 2x RPi4 now.
Other option is to load start4_cd.elf (Cut-Down) that has no DSP functions enabled AFAIK, but not sure about that, never used it.
