Public bug reported:
Hardware: Bose QC35 II
When selecting the A2DP Sink profile these headphones work fine.
However, with HSP/HFP selected neither the output nor the microphone
work. The headphones will periodically say "Call from" and then break
off, and also you can hear a low grade crackling like line noise in them
the rest of the time.
Potentially relevant logs:
dmesg (the second message is repeated frequently):
[ 68.288408] input: 2C:41:A1:80:A1:C4 as /devices/virtual/input/input21
[ 78.575027] Bluetooth: hci0: last event is not cmd complete (0x0f)
Originally, I got an error like the following from ("journalctl -u bluetooth"),
but then ran "rfkill unblock bluetooth" which seems to have fixed it:
May 13 15:58:02 skylake bluetoothd[1023]: Failed to set mode: Blocked through
rfkill (0x12)
May 13 15:58:19 skylake bluetoothd[1023]: Failed to set mode: Blocked through

May 13 16:00:41 skylake bluetoothd[1023]: Unable to get io data for Phone Book

What additional information would be useful to debug this?
