mitu Posted September 7 Posted September 7 I have an Orange Pi 5 board, installed with the 25.8 Debian Bookworm + Cinnamon desktop system. I have switched (using armbian-config) to the edge kernel in order to test the HDMI audio support in the new Linux kernel, but I'm not getting any audio out. The ALSA HDMI card seems to be present (see below), but there's no sound using speaker-test or aplay.

Is there anything extra that should be configured in order to get audio output ? Output from armbianmonitor - https://paste.armbian.com/gegorimako 0 Quote
IBV Posted September 7 Posted September 7 Hi, always check with "amixer" (alsa mixer) if your outputs are not muted. 0 Quote
mitu Posted September 7 Author Posted September 7 amixer doesn't show any controls on the first card (and so does alsamixer) - amixer -c 0 shows nothing, while amixer -c 1 has a lot of output, but I think it's just showing the controls for the rockchipes8388 audio card (the analog output, not the HDMI). 0 Quote
Dantes Posted September 7 Posted September 7 On what kernel version are you ? HDMI Audio was introduced in the Linux Kernel in 6.15-rc1 0 Quote

IBV Posted September 7 Posted September 7 aplay -D plughw:0,0 -f S16_LE -r 48000 -c 2 your_audio_file.wav ? this will force a more common audio format (in case the monitor supports specific audio formats. If not working, no idea, hw detection looks ok. 0 Quote

IBV Posted September 8 Posted September 8 Do you get sound (HDMI) through your monitor speakers with the official vendor image? 0 Quote

I haven't tried the vendor image, but I have another SBC (RasPi4) that can succesfully output audio through the monitor speakers, so the monitor is ok. I could re-test the HDMI cable I guess, but since the video signal is ok I don't expect the audio to have issues. 0 Quote
IBV Posted September 9 Posted September 9 I suggest to confirm first that it works with the vendor image, just in case. If you boot the vendor image you could also gather some info, like aplay -L, etc. 0 Quote

mitu Posted September 9 Author Posted September 9 OK, so I installed the latest Debian/Trixie + Cinnamon + vendor kernel available and audio is working. The name of the cards and mixers are different though: Quote $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: rockchipdp0 [rockchip-dp0], device 0: rockchip-dp0 spdif-hifi-0 [rockchip-dp0 spdif-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: rockchiphdmi0 [rockchip-hdmi0], device 0: rockchip-hdmi0 i2s-hifi-0 [rockchip-hdmi0 i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: rockchipes8388 [rockchip-es8388], device 0: dailink-multicodecs ES8323 HiFi-0 [dailink-multicodecs ES8323 HiFi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 $ aplay -L null Discard all samples (playback) or generate zero samples (capture) default Playback/recording through the PulseAudio sound server lavrate Rate Converter Plugin Using Libav/FFmpeg Library samplerate Rate Converter Plugin Using Samplerate Library speexrate Rate Converter Plugin Using Speex Resampler jack JACK Audio Connection Kit oss Open Sound System pulse PulseAudio Sound Server speex Plugin using Speex DSP (resample, agc, denoise, echo, dereverb) upmix Plugin for channel upmix (4,6,8) vdownmix Plugin for channel downmix (stereo) with a simple spacialization hw:CARD=rockchipdp0,DEV=0 rockchip-dp0, rockchip-dp0 spdif-hifi-0 Direct hardware device without any conversions plughw:CARD=rockchipdp0,DEV=0 rockchip-dp0, rockchip-dp0 spdif-hifi-0 Hardware device with all software conversions sysdefault:CARD=rockchipdp0 rockchip-dp0, rockchip-dp0 spdif-hifi-0 Default Audio Device dmix:CARD=rockchipdp0,DEV=0 rockchip-dp0, rockchip-dp0 spdif-hifi-0 Direct sample mixing device usbstream:CARD=rockchipdp0 rockchip-dp0 USB Stream Output hw:CARD=rockchiphdmi0,DEV=0 rockchip-hdmi0, rockchip-hdmi0 i2s-hifi-0 Direct hardware device without any conversions plughw:CARD=rockchiphdmi0,DEV=0 rockchip-hdmi0, rockchip-hdmi0 i2s-hifi-0 Hardware device with all software conversions sysdefault:CARD=rockchiphdmi0 rockchip-hdmi0, rockchip-hdmi0 i2s-hifi-0 Default Audio Device dmix:CARD=rockchiphdmi0,DEV=0 rockchip-hdmi0, rockchip-hdmi0 i2s-hifi-0 Direct sample mixing device usbstream:CARD=rockchiphdmi0 rockchip-hdmi0 USB Stream Output hw:CARD=rockchipes8388,DEV=0 rockchip-es8388, dailink-multicodecs ES8323 HiFi-0 Direct hardware device without any conversions plughw:CARD=rockchipes8388,DEV=0 rockchip-es8388, dailink-multicodecs ES8323 HiFi-0 Hardware device with all software conversions sysdefault:CARD=rockchipes8388 rockchip-es8388, dailink-multicodecs ES8323 HiFi-0 Default Audio Device dmix:CARD=rockchipes8388,DEV=0 rockchip-es8388, dailink-multicodecs ES8323 HiFi-0 Direct sample mixing device usbstream:CARD=rockchipes8388 rockchip-es8388 USB Stream Output speaker-test worked both by specifying the mixer (... -D plughw:CARD=rockchiphdmi0,DEV=0) or through PulseAudio's ALSA emulation after setting the default sink to the rockchiphdmi0 card. The list of audio cards is different in the vendor kernel than what's available OOB with the edge kernel, so I'm not sure if the configuration is comparable. But the audio port/cable combo seems to be fine so there's that.. 0 Quote
