March 27, 20251 yr 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?

March 27, 20251 yr There was no official audio routing for the h616 until recently and still none yet for HDMI. As far as I know? https://lore.kernel.org/linux-arm-kernel/20241023075917.186835-1-ryan@testtoast.com/T/ I believe there is unofficial patching for it available in Armbian for 6.6.y, but I never added the required nodes to test it. This would be why there is no functional audio on the unit as of yet.
March 27, 20251 yr Author 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) ?
March 27, 20251 yr I'm waiting for the HDMI part of the audio patch to drop. There is currently discussion going on about the Audio in a private chat, concerning 6.12.y and up, but I haven't seen consensus yet. Once its reached, I will drop in the nodes. This could take time.
June 2, 20251 yr 1 час назад, -jk- сказал: Is there any news for HDMI audio on this board? Audio output via HDMI should work on all H616-H618 devices. This was tested on the bananapi-m4-berry board for current and edge kernels. In the pulseaudio settings applet, you need to make several switches back and forth (turn on/off) for the sound to appear. Tested on gnome, ubuntu.
June 2, 20251 yr The analog audio output to the connector that is soldered to the board does not work for some reason. Although there is a code in the core, there is also a node in the DTS.
June 2, 20251 yr Thanks! Just run upgrade to 6.12.30 - and sounds works! (on 6.12.20 was no sound card in aplay -l )
