No sound on nanopc t4
Trying to get sound working on my t4. Looks like pulseaudio detects the realtek rt5651-codec but I can't get any sound out of it. The software mixer seems to be showing audio, I just can't hear anything
nanopct4 4.4.161-rk3399 SMP
aplay-l shoulws realtekrt5651co as device0.
Any help debugging this would be great.
Regards,

Here is a way to get the onboard audio working on NanoPC T4 (and probably M4 too). It kind-of works with pulseaudio, but I think more work is needed for a good solution for pulseaudio (need to develop a UCM profile). The attached asound.state file will configure the rt5651 codec mixer with sane settings. To use it:
Download the attached asound.state.draft.201902018
Run the following command from a terminal (in whatever directory you downloaded the file):
alsactl --file ./asound.s
