Hey, I just installed pi musicbox on my raspberry pi 2b but for some reason, I can’t get it to stream any audio. I have tried streaming from youtube, google play music and the built in radio stations but I can’t get any audio out of it. I have tried using both the 3.5 mm headphone jack on the pi but also a cheap 3.5 mm USB sound card. Any ideas on how to fix this?
Do you have an HDMI cable plugged in when you boot? If so, try removing the HDMI cable and rebooting and see if the audio port is now working.
