I am trying to use a Bluetooth speaker & mic combo for my audio input and output for the raspberry pi 4b. The speaker works for audio output no problem, but when it comes to audio input I keep getting this error; Failed to connect to Bluetooth device - Could not set profile for device:Input/Output error. I know the Bluetooth speaker/combo works because when I tried it on another device it worked fine. I would appreciate any suggestions, have a wonderful day.

  • IIRC, the speaker will need to be declared as an audio sink; the mic as an audio source. Try searching for something like bluetooth profile source sink – Seamus Dec 29 '20 at 1:05
  • Thank will look into that more – Jhon Dec 29 '20 at 3:22
