I am very happy to have my second rock960 from seeed. I mounted it inside a mechanical keyboard for an all-in-one solution, and I like it a lot. I have an issue though.
In both the built-in Android or Debian on SD card, I get no audio from HDMI.
In Android settings, the audio device choices are SPDIF or HDMI Bitstream. I tried both, but did not have luck, even after rebooting. The first time I opened this setting, neither one was selected.
In Debian, in PulseAudio volume control, the only output device shown is “ROCKCHIP,SPDIF Analog Stereo” … turning the volume all the way up and playing a song, I see a level indicator moving, but no sound.
I can’t try this on my other board because I accidentally damaged it while desoldering some connectors.
Any advice is appreciated!
