Review of NanoPi NEO2: World's Smallest Audio Streamer

[Aldoszx]

Yes, you are right. I have to extract some logs.

You may also want to try playing music via some local player in order to test basic audio functionality without roon bridge.

I am gonna try that also.
But i have this "ROON infrastructure" already in place and i am very happy with it.
I will try another OS, like Ubuntu or Armbian.

I meant to try that just for testing.

Yes, maybe MPD or something.
There are not so many OS-es for NEO2.

Exactly. MPD with DietPi would be the first thing I would try.

I don't use Roon, but I tested it. It worked. Here are my OS images

Tank you. I will try it.
I have also the OLED module, so do you think the script and driver could be included also into your image?
On DietPi I am using this https://dietpi.com/phpbb/download/file.php?id=1519 but slightly modified in order to put the startup script on /var/lib/dietpi/postboot.d/
Another approach could be to create a systemd service

 

[bzfrp]

I don't have the OLED module to test.
The startup scripts are all in /etc/init.d/.
If the image works for you, you can try to add your script (and driver).

 

[Aldoszx]

Ok, thanks. I will try, but i think it needs some dependencies and i don't know you have those already installed.
Also, the script compiles some things and don't know it is possible in your image.

 

[bzfrp]

You are right. Indeed I have compiled a minimal OS image.

 

[Aldoszx]

You are right. Indeed I have compiled a minimal OS image.

Could you please recompile another one including the script for OLED?
I don't have in place a linux machine to do it by myself.

 

[bzfrp]

I can try to recompile another one if the current OS image (the one for roonbridge?) works already for you.
Could you please test it ? It seems that this image may not work depending on network configuration (dhcp problem).

His issues were occasional dropouts and distortion. DHCP issue would probably result in total silence.

 

[bzfrp]

My old OS images may have a problem connecting to the router via dhcp.
To fix it, try to add an option
udhcpc_opts -t 5
in /etc/network/interfaces

Thank you.
I will try the image and come back with feedback.

Do you think a normal Raspberry Pi will measure that good as well? I've read somewhere that it shares usb and ethernet on the same bus so it could be noisy. I have a RP 3 so not the latest.

It will not be noisy but it will suffer from occasional dropouts. It worked fine for me with Volumio but it started to make problems when I activated brutefir.

With I2S DACs it works perfectly well.

Thank you. I was planning to use RoPieee.

Brutefir certainly does something that triggers the dropouts, unless you pin it to a single cpu core. I gather there's something else that's often running on Volumio that triggers it too, but I forget what (database?). I've not had dropouts on PiCorePlayer despite trying to trigger them. Not tried with RoPieee.

Correct - the dropouts are a USB thing.
