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, Cam
