Thank you. The latest eMMC image that I can find is https://drive.google.com/drive/f ... gAqAX2oyZkg2QVQwZjA and I'm currently using this (which has audio issues)

Could you please point me to the latest Ubuntu image on Google Drive?

Hi leung先森,

I compiled the latest kernel and I can see the sound card now. However, when I play a wav file using "aplay file.wav" command, I couldn't hear anything on my headphone. I tried increasing the gains, but no luck.

Maybe there are some alsa mixer controls needs to be set. Could you please share details on the alsa mixer controls for playback and record?

Thanks,
San
