Audio on NanoPi K1 Plus

Recommended Posts



I found that on NanoPi K1 Plus there is issues with both of integrated audio adapter (H3 Audio Codec) and HDMI Audio (allwinner-hdmi 1c22800.i2s-i2s-hifi)

1. With H3 Audio Codec I getting only silence, altrought there is short click on starting and end of playback. "Stereo" mode was chosen in pavucontrol for this audio adapter.

2. With allwinner-hdmi audio playback is working, but left and right channels is swapped. Like above "Stereo" mode was chosen in pavucontrol for this audio adapter.

Tests was performed from Mate desktop installed on top of Armbian 20.05.4 with Linux 5.4.45-sunxi64. "speaker-test -t wav -c 2" command was used for testing. To make sure that PulseAudio will route audio from speaker-test to right audio adapter I used pavucontrol to disable all other audio adapters besides the one I currently test.


I wonder if anyone else experiencing same issues with this board? Should I report allwinner-hdmi channels issue or H3 Audio Codec issue to kernel bugzilla or some Armbian-specific patches is involved in enabling audio adapters on this board?
