Bug 506024 – net-wireless/bluez-5.16 with media-sound/pulseaudio-5.0 - Bluetooth failures for A2DP headphone connection

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Sumit Khanna 2014-03-28 03:33:10 UTC]

I had a problem with pulseaudio-4 and A2DP so I kept it masked until recently; decided to get everything current. I'm mostly in amd64, but I pulled bluez from ~amd64 in hopes of fixing this issue. 

If I try the following:

$ bluetoothctl 
[NEW] Controller 00:02:72:35:41:B4 sumblue [default]
[NEW] Device 34:DF:2A:09:A5:D0 Velodyne vFree

[CHG] Device 34:DF:2A:09:A5:D0 Connected: yes

It says successful, but no more commands will run and if I look at the klog, 

[  174.634534] input: 34:DF:2A:09:A5:D0 as /devices/virtual/input/input8

and syslog:

If I /etc/init.d/bluetooth restart while leaving bluetoothctl open:

I recompiled my kernel with uinput and tried both vmlinuz-3.13.7-gentoo and vmlinuz-3.12.13-gentoo. I've searched countless forums about this in Gentoo, Ubuntu and Arch and nothing I've found seems to work. I continually get the segfault. This did work with pulseaudio-2.1-r1 and the older net-wireless/bluez-4.101-r8 (was using blueman, but unmerged that since there is no bluez-5 version; pretty much the same as bluetoothctl with GUI so no big deal...similar results with Bluedevil which serves the same purpose)

This might be totally unrelated, but gdm never started for me either. I get a blank screen occasionally a screen with a clock I can't interact with. A few months back I just switched to xdm, but I'm wondering of the "Activated service 'org.freedesktop.NetworkManager' failed: Launch helper exited with unknown return code 1" is somehow related (saw things in various forum posts). 

Also in case needed, my Bluetooth adapter info:

and a Kernel bugzilla post in case it's at the kernel layer (some people report these types of errors going away if dropping back to 3.11.x, but I haven't tried that yet):

Kernel config (/proc/config.gz) in case it's kernel related

[Comment 2 Pacho Ramos 2014-03-30 07:30:13 UTC]

Running bluetoothd -d as suggested in https://bugzilla.kernel.org/show_bug.cgi?id=73061#c3 would help. Also, you could probably take a better backtrace:
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces

Additionally, you could install abrt to let it catch the backtrace for you (once enough packages are recompiled with debugging symbols)

btmon logs

[Comment 4 Sumit Khanna 2014-03-30 22:50:04 UTC]

I tried stopping the bluetooth service and running it manually with -d, but there was no debugging output or new stuff in the system/kernel log that I could see. 

I ended up getting everything working by removing the bluetooth USE flag from all the gnome packages I use, masking Pulseaudio-5 (going back to Puselaudio-2, bluez-4 and blueman).

I know that's a bad fix, but I'm going to keep kicking the can.

[Comment 5 Pacho Ramos 2014-03-31 20:09:08 UTC]

Please forward the btmon output to upstream too as they requested it and will surely give them more usefulness than me ;)

[Comment 6 Sumit Khanna 2014-03-31 21:17:19 UTC]

btmon logs have been added upstream.

i have a working A2DP experience using bluez-5.15 and pulseaudio-5.0.

How does pulseaudio-5.0-r2 work with bluez-5 and bluez-4?
