On 18.04, I'm having this same issue. I can pair to an Echo, but cannot connect nor setup as an Audio Sink. I get errors like "dbusfailederror input/output error" in blueman.

I believe the issue is related to the fact that Amazon Echo is paired as a handset (i.e., speaker + microphone) rather than just as a speaker. I believe the critical error is found in a dmesg line such as: Feb 28 10:59:05 n1 bluetoothd[1025]: a2dp-source profile connect failed for 50:F5:DA:A6:3F:EA: Device or resource busy as I describe in the askubuntu.com discussion at: https://askubuntu.com/questions/871630/cant-send-audio-to-amazon-echo- via-bluetooth I have clarified there my thinking and the steps I've taken thus far on this issue, which includes trying debug bluetooth per the Ubuntu wiki page which describes how to do so. This is probably an upstream issue, as Mike H-R has commented there that the problem also occurs on ArchLinux. I and a few others would like to get this resolved, and I am happy to help (I'm a software developer). However, at this point, I'm not sure how to proceed without some assistance. I suppose I could report it to Debain, but I've only ever used Debain vis a vis Ubuntu, so I thought it best to start here. Thanks.
