I am struggling with making my Bose Quiet Comfort 35 headset work on my XPS 15 9550 running Arch Linux. The headset works on my other computer (also running Arch), but I just can't figure out how to make it work on this laptop...
I first installed pulseaudio-bluetooth, bluez, bluez-libs and bluez-utils, then enabled and started the bluetooth service, without errors. I then set "ControllerMode=bredr" in "/etc/bluetooth/main.conf", restarted bluetooth and attempted to pair using blutoothctl. This failed, and led me to believe some firmware was missing. Installing bluez-firmware changed nothing, so I downloaded and installed the firmware for my card: aur.archlinux.org/bcm20702a1-firmware.
The headset pairs and connects now, but the connection is always and immediately dropped:
Device 04:52:C7:77:81:E3 Bose QuietComfort 35 [CHG] Device 04:52:C7:77:81:E3 Connected: yes [CHG] Device 04:52:C7:77:81:E3 Connected: no
The same thing happens when using "blueman-applet", with the following error:
Connection Failed: blueman.bluez.errors.DBusFailedError: Input/output error...
In journalctl the following error appears:
Aug 20 21:38:18 duty bluetoothd: Endpoint replied with an error: org.freedesktop.DBus.Error.AccessDenied
Running "blueman-applet" as sudo reports the following error:
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NotSupported: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead
Running "bluetoothctl" as sudo yields the connection followed by immediate disconnection result.
I've tried following suggestions from similar threads and mess around with "/etc/bluetooth/audio.conf", but to no effect.
I'm guessing it's a problem related to "pulseaudio-bluetooth", but am unable to debug any further, as I don't know what else can be done, nor where to look for more detailed error reports.
Might be worth noting that running "sudo pactl load-module module-bluetooth-discover" yields the following errors:
Connection failure: Connection refused pa_context_connect() failed: Connection refused
Any help is much appreciated...
