I have a similar Issue. Banana Pi M5, with Armbian Jammy XFCE desktop. the alsamixer gui shows only a dummy output.
aplay -l shows the following
root@bananapim5:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: BPIM5 [BPI-M5], device 0: fe.dai-link-0 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: BPIM5 [BPI-M5], device 1: fe.dai-link-1 (*) []

Subdevice #0: subdevice #0
card 0: BPIM5 [BPI-M5], device 2: fe.dai-link-2 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
alsactl init creates the following output, without changing anything on the aplay output.
root@bananapim5:~# alsactl init

I need HDMI Audio, but so far I could find no way to enable any audio output.
