Hi there @saxonpaul92 and welcome to the forums! Thanks for trying balenaSound.
If you happen to be using Windows, it looks like the issue you’re seeing is the same as this one: Can´t find my device when searching for bluetooth devices
The solution is to change your local git configuration to retain line endings, see here: https://stackoverflow.com/questions/10418975/how-to-change-line-ending-settings
Alternatively you can download the .zip file of the project instead of using git.
Let me know if this helps
