Hi!!!
Few days ago I found the great world of digital audio player based on RPi. It is amazing. I’ve tried different builds but decided to stay with Volumio. It is more user friendly I can say . I will continue my experiments and will try to help you to make it better )) Nice work!!!
I found some problems with third party plugins so far Youtube plugin don’t want to play 90% of content. Spotify plugin crash and don’t want to uninstall. I will try to contact authors and find the causes.
But one more time thanks for your project!!!
Dmitry!
I have just found great Documentation for Volumio!
And even more )))))))))))))) that it is based on NodeJS + AngularJS
I’m a Salesforce/Python/NodeJS developer with few years AngularJS skills and Raspberry Pi is my hobby.
Volumio is great opportunity to me to spend my free time ))))))))))
