Hi, I just got my BPI-M4 Zero running, however I do not know how to get HDMI Audio output working (if it's possible at all)
I installed:
- Armbian_25.2.0-trunk.414_Bananapim4zero_trixie_current_6.6.72_minimal.img
# uname -r
6.6.72-current-sunxi64
# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Armbian 25.2.0-trunk.414 trixie
Release: n/a
Codename: trixie
# aplay -l
aplay: device_list:279: no soundcards found...
# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
pipewire
PipeWire Sound Server
default
Default ALSA Output (currently PipeWire Media Server)
# pacmd list-sinks
No PulseAudio daemon running, or not running as session daemon.
# pactl info
Connection failure: Connection refused
pa_context_connect() failed: Connection refused
Is it possible? And if so, do I need some additional drivers or packages, or what do I need to configure?
Edit: More Info:
