Review of NanoPi NEO2: World's Smallest Audio Streamer

[somebodyelse]

What's your build process for the image?

In buildroot "make menuconfig", Filesystem images,
[*] initial RAM filesystem linked into linux kernel

BR2_TARGET_ROOTFS_INITRAMFS:
Integrate the root filesystem generated by Buildroot as an
initramfs inside the kernel image. This integration will
take place automatically.

I recently set up a NEO3 as a portable DLNA server, attached to a boombox.
If anyone here is interested, the full story is on diyaudio -

Hi folks,
Need some ASR brain power. I just received Neo3 install dietpi and GMediaRender. Dietpi shows up on my network and as an end point from my media app. But it won't play. I start a song and it stops almost immediately. Do I have to do anything with the USB to get it to output audio?

Some steps would be really helpful.

When you login to the Neo3 and run `aplay -l`, what do you see? Does this show you the right DAC.

 

[NiagaraPete]

Yes it shows the correct DAC. So I guess its working.

I get this:

card 1: Pro [D30 Pro], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

 

[dsnyder0cnn]

Cool. I wonder if the volume is just down. Try running `alsamixer` and making sure levels are up to 100%

 

[NiagaraPete]

root@DietPi:~# alsamixer
cannot open mixer: No such file or directory

 

[dsnyder0cnn]

root@DietPi:~# alsamixer
cannot open mixer: No such file or directory

Looks like your USB interface is card 1, so show this:

alsamixer -c 1

 

[NiagaraPete]

It seems be correct.

You should see something like this:

Just make sure the levels are up for all of the "sliders." Note: you may have scroll to the right to see all of them (right arros key)

It seems be correct.

I suspect that you may have to tell GMRenderer which card to use. This doc has some tips:

gmrender-resurrect/INSTALL.md at master · hzeller/gmrender-resurrect

Resource efficient UPnP/DLNA renderer, optimal for Raspberry Pi, CuBox or a general MediaServer. Fork of GMediaRenderer to add some features to make it usable. - hzeller/gmrender-resurrect

github.com

Essentially, use "aplay -L" (upper-case "L") to get the name of the device…it may not be "sysdefault".

You'll need to track down the script that is starting the process and possibly change the device to match your audio interface. This command may be useful to help you identify which file to edit:

grep -Frl gstout-audiodevice /etc

If all of that is too much of a pain, you can use my trial code to start a Roon subscription. ;-)

I have a NanoPi NEO2, and it makes a very nice little Roon endpoint.

 

[NiagaraPete]

This is what I see.

 

[NiagaraPete]

Okay. I very much appreciate your help. I'll look at the doc. I may try roon as well. I do have roon on my NAS.

Thanks

Hi,
Thanks for your help and the link. I missed one step in the setup and its working now. Personally I don't see the value in ROON for my purposes but it truly is a great system.
Cheers
