NanoPi Neo Sound through header

[Johhny Blue]

Hi All.

 

First post here (and quite a newbie).

 

I have installed Armbian on my new NanoPi Neo and followed the instructions. It is all booting OK and I now wondering how I can attach a speaker directly to the header

10 LINEOUTR LINE-OUT Right Channel Output

11 LINEOUTL LINE-OUT Left Channel Output

12 GND 0V

 

Will this work?

How can I test it as I cannot see it with ALSAMIXER.

 

TIA.

Hi

I don't know the details of the NanoPI but I doubt it is safe to drive a speaker from it.

You have to use an amplifier like those powered by USB that are used with PC sound cards.

Even driving long wires with ports not specially designed for that, like Ethernet or USB, is a mistake

so for best results the amplifier must be close to the CPU.

Sure, it is connected to amplified speakers, but I cannot see it using aplay -L or in alsamixer.

Can someone tell me how to enable it (or even if it is there)

I can't see it loaded as a module either?

Thanks.
