Support for AudioInjector.net Stereo board?

[jrbean67]

Has anyone tried configuring the AudioInjector.net Stereo board for use with this image?

I'm about to give it a try. I have a few of these that I can share with friends, and only one low latency USB interface.

My target app at this point is Sonobus, since I don't have any Jamulus servers nearby to use. The image is really cool - I've never used a system that had VNC configured like that.

Thanks,
John

That's because there has never been a system that had VNC configured like that. noVNC has been around for a while, but urlrelay to redirect to it is my innovation.

I haven't heard of anyone using that board yet, so give it a try.
I'm guessing you'll need to edit /boot/config.txt to disable internal audio, and use audioinjector device tree

#dtparam=audio=on
dtoverlay=audioinjector-wm8731-audio

You should be able to lower the value of NPERIODS in /etc/jackdrc.conf to reduce latency, may as low as 2 for that card.

That's because there has never been a system that had VNC configured like that. noVNC isn't so well known but it has been around for a while. The use of urlrelay to redirect to it based on source IP is my recent innovation.

If you want to do peer-to-peer and are in the mood to experiment, you could also check out jacktrip, which is also installed but I haven't tested it. There's a wrapper for it called jamtrip that can also be installed from my repo: "sudo apt-get install jamtrip", then run jamtrip from command line. You should probably stop jack service first (sudo systemctl stop jack).
