Buster + IQaudIO card

[NickSutton]

Hey, Firstly great job! I decided to see what I could get working before ordering a new set of parts for this. I’m currently building an AirPlay speaker solution using Shairport-Sync and have that working well. I’d like to add your awesome visualisation setup to my project, but have a couple of questions:

1) I’m running raspbian buster and some of the files to do with audio config you describe no longer exist :-(

2) To get decent audio quality I’m using an iQaudioIO Pi-DAC board, I plugged in a USB mic/speaker dongle I had laying around and added a splitter to the IQaudIO output and surprising the USB mic (wired to the output of the iQaudioIO splitter) did record, so that’s promising that the pi can get the output back as the input for the visualisation.... However, when I ran some of the test .py files, my audio output stopped completely and had to be rebooted before it was happy.... Is there a way to get the two to play nicely together?

3) I’d like to see this setup working before I buy the LEDs, how do i run the GUI on the pi?

Great work on your project! Cheers, Nick

[NickSutton]

Just by way of an update, question 1 was resolved by actually downloading the repo, so that helped!

Question three I guess I’m asking can I run the GUI without the LEDs installed? St the minute it craps out with pages of errors related to the IQAudio device (will copy when I’m back on the machine).

I feel optimistic!

You are able to run the GUI and it will display even if there is no Arduino connected, it basically just sends the UDP packets to a nonexistent device and so they get discarded but sometimes I just like to run the GUI because it looks cool even without the lights.

Thanks, should have mentioned, am looking at using pi in standalone mode!

Hey, so here’s what happens when I run sudo python visualisation.py

As stated I’m using Shairport-sync to receive the audio from iPhone to Raspberry Pi (working well) And I’m physically feeding the audio output from the IQaudio pi-DAC+ to a USB mic in.

Any ideas?

Here is my aplay -l output showing both of the cards (IQaudIO for output, and USB audio for the mic) correctly loaded, so I’m not sure why I’m seeing so many errors?:

**** List of PLAYBACK Hardware Devices **** card 0: IQaudIODAC [IQaudIODAC], device 0: IQaudIO DAC HiFi pcm512x-hifi-0

What did you end up doing to solve it?

[NickSutton]

Followed the instructions properly! I had been avoiding setting the USB audio device as the default because I’d like to use my IQAudio card as the output, but that’s for another day.

Glad to see it working, now just need to tweak it to my own set up
