Title:
Can't send audio to Amazon Echo via Bluetooth
Status in bluez package in Ubuntu:
Confirmed
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
Pairing and coupling to Amazon Echo works, but no sound is heard.
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.
