Audio does not work on RPI 3 B+ (Jack 3.5) #101

I use bcmrpi3_defconfig to rebuild kernel version 4.19. I get kernel source at https://github.com/raspberrypi/linux

When I run command aplay -l. It show strange output. There is no HDMI cable connected to raspberry.

$ aplay -l List of PLAYBACK Hardware Devices card 0: vc4hdmi [vc4-hdmi], device 0: MAI PCM vc4-hdmi-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0

And Audio on 3.5 Jack not working too.

Hi @NguyenTrongThinh

What do you have in /boot/config.txt?

Does it work for you if you use one of my binary kernels (bcmrpi3-kernel or bcmrpi3-kernel-bis)?

Also see my note here.

Best, sakaki
