NanoPi M4 : No sound (Solved)



Hi all, I'm using the @pask build for the M4 v2 and all seems good except I am not getting any sound from the 3.5 Jack ( can't try the HDMI as I don't have anything to plug in ) any ideas chaps ?


Edit - this is the output from mplayer

Thanks for replying but I'm a user not a kernel hacker :-) that stuff doesn't mean much to me - are you saying anything using kernel 5 or above has no sound ?




Yes, sound with kernel 5 and above is being worked on as written in this thread.
