Thank you for the explanation. Is there a realisitic chance for it to be added in the near future? And could I assist with that? Or should I look out for alternatives (e.g. usb soundcard/speaker) ?

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?
