I thought it my be the hat but I have another one and I switch it and I get the same thing so it must be the NanoPi-NEO-Air. I had to solder the pins on it and I looked at them real good and they seem like they are all good. The RS232 works on it that's how I got this text. But do have it on WiFi too.

Any one know what could be wrong?

The green LED is lit on the sound board. I guess that says it should be working.

you need the right linux image with support for the pcm5102a hat.
which image do you use?

you could also take a look here:

I used "nanopi-neo-air_eflasher_friendlycore-xenial_4.14_armhf_20181120.img" does this one support the PCM5102A?

As it booted up I seen:

[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.

So I did that and got this back:

root@NanoPi-NEO-Air:~# systemctl status systemd-modules-load.service

I guess it does mean that this kernel don't work with the PCM5102A sound hat.

Can a do some modprobe something like that?

did you enable I2S0 and the PCM5102A with npi-config like written in the Wiki about the PCM5102A?:

I got it working!

Looked at http://wiki.friendlyarm.com/wiki/index.php/NanoHat_PCM5102A

Starting at "5.2 Under H3/H5 & Linux-4.x Kernel" I did npi-config and picked how they show in the photos there. Rebooted and did aplay /root/Music/test.wav -D plughw:4 and it plays music now.

Not sure why it install it as card 4.

Did not have to change the kernel looks like.

DEV=0 or 1 but never any thing saying DEV=4

Is there a way to fix this?

whats the output of
aplay -l
and what is the content of your /etc/asound.conf ?
Sometimes after installting the pcm5102a - in mainline armbian - and reboot my pcm5102a changed from Card 0 to Card 1:

Code: Select all

my /etc/asounf.conf :

The file /etc/asound.conf looks like this. Wow says card 4 I will change it to 0 and maybe that will work.

pcm.!default {
type hw card 4
}
ctl.!default {
type hw card 4
}

I copied what you had in the /etc/asound.conf file and rebooted.

But it still says card 4 like this:

I checked the /etc/asound.conf and it's still how I changed it to what you have.

Got this because I want to install it in a sound bar. But have to get it working good 1st.

It list a lot but none are DEV=4

I don't know how it get's it's device list. Maybe it can't go up to 4 only 0 and 1 not sure.

isnt that device-name useable without device-numer?

in this thread they used on a RPi the follwoing name for a card:

Code: Select all

~/squeezelite $ ./squeezelite -o sysdefault:CARD=GenericRJ -a 20:4:16:1 -s 192.168.1.13
"16" in -a 20:4:16:1 means force 16 bits

With Squeezelite I get a software volume 
0 => no sound
1=> sound not weak, noisy
from around 12, the sound become less noisy but it is already very loud 
20=> is close to max before the amp clips
