I have these enabled, card is present in /proc/asound/cards, but
alsamixer doesn't work with it.

I'm running 5.4.0-rc6 (commit
00aff6836241ae5654895dcea10e6d4fc5878ca6) with your patch "arm64: dts:
rockchip: add analog audio nodes on rk3399-rockpro64" on top of it.

Similar here:

[vasilykh@rockpro64 ~]$ dmesg | grep -i asoc
[ 15.627685] asoc-audio-graph-card sound: ES8316 HiFi <->
ff890000.i2s mapping ok
[ 16.250196] asoc-simple-card hdmi-sound: i2s-hifi <-> ff8a0000.i2s mapping ok

Same here:

[vasilykh@rockpro64 ~]$ cat /proc/asound/pcm
00-00: ff890000.i2s-ES8316 HiFi ES8316 HiFi-0 : ff890000.i2s-ES8316

Same here.

Same here.

Yet alsamixer doesn't work for me. It terminates with 'cannot load
mixer controls: No such device or address'. Strace shows that fails
here:

openat(AT_FDCWD, "/dev/snd/controlC0", O_RDWR|O_CLOEXEC) = 3
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
ioctl(3, SNDRV_CTL_IOCTL_PVERSION, 0xfffffd3ad04c) = 0
fcntl(3, F_GETFL) = 0x20002 (flags O_RDWR|O_LARGEFILE)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK|O_LARGEFILE) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_LIST, 0xfffffd3ad228) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_LIST, 0xfffffd3ad228) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_INFO, 0xfffffd3ace38) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_READ, 0xfffffd3ac160) = -1 ENXIO (No
such device or address)

Looks like it fails to talk to the codec?

mpg123 thinks that it's playing audio, but my headphones connected to
3.5mm output are silent.

Vasily
