There is no Headphone as a sound card in my Rpi Zero 2.
aplay -L gives back the following:
null
Discard all samples (playback) or generate zero samples (capture)
hw:CARD=b1,DEV=0
bcm2835 HDMI 1, bcm2835 HDMI 1
Direct hardware device without any conversions
plughw:CARD=b1,DEV=0
bcm2835 HDMI 1, bcm2835 HDMI 1
Hardware device with all software conversions
sysdefault:CARD=b1
bcm2835 HDMI 1, bcm2835 HDMI 1
Default Audio Device
dmix:CARD=b1,DEV=0
bcm2835 HDMI 1, bcm2835 HDMI 1
Direct sample mixing device
This is just strange for me, I have tried to force 3.5mm output in dietpi-config, but then I get no devices at all, tried changing cmdline.txt with “snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_compat_alsa=0” but it doesn’t have any result.
My config.txt is the following:

#hdmi_safe=1
# Uncomment to adjust the HDMI signal strength if you have interferences, blanking, or no display.
# - Ranges from "0" to "11", use values above "7" only if required, e.g. with very long HDMI cable.
# - Default on first RPi1 A/B is "2", else "5", on RPi4 this setting is ignored.
