module-bluetooth-discover does not load on login

[Paul Natsuo Kishimoto]

The following lines appear in /etc/pulse/default.pa, which I have not modified:

.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif

Expected: module-bluetooth-discover is loaded on login, as configured.

Observed: pulseaudio's module-bluetooth-discover does not load on login. My system does not detect and set up sinks when I connect to Bluetooth devices (including an A2DP speaker and a headset).

If I issue, in a terminal window:

$ pactl load-module module-bluetooth-discover
24

…then the devices are detected and sinks set up correctly.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[David Roberts (dave-roberts20)]

When logging on or restarting pulse audio this message appears in my syslog

pulseaudio[2727]: [pulseaudio] module.c: Module "module-bluetooth-discover" should be loaded once at most. Refusing to load

The discover module is not loaded though.

Manually loading it later with pactl works fine.

[gvlists (gvlists)]

If it helps, here is some additional information. I observed this problem with my Samsung HS-3000 headset when used with a bluetooth USB dongle which has a CSR LE chip in it. I did not have the same problem previously when I used a Nokia BH-100 headset with Samsung NC20 netbook.

[Jim Ford (jaford)]

I don't even have module-bluetooth-discover on my Xubuntu 13.10 system!

[Anthony (p-ubuntu-t)]

Same issue, and workaround applies on 14.04.

[Tim Passingham (tim-8aw3u04umo)]

This is driving me potty.

It seems I first have to attempt to connect the sink using Blueman, which fails with "Connection Failed: Stream setup failed"

I then use pactl to load the module-bluetooth-discover, and attempt reconnection, which usually works.

If I do these two thing the other way round it does not work.

This is horrible. All I want to do is listen to something. It should 'just work' once all the right software is installed and the device is paired.

[Pouer (pierre-lalouer)]

Same problem and same ,long to apply, workaround on Xunbuntu 14.04
This bug is reported as "unassigned" does it means that nobody is dealing with it?

[Mathieu Trudel-Lapierre (cyphermox)]

module-bluetooth-discover is installed by default on most Ubuntu installs, and as such should be working out of the box. If it's not loading on startup but loads if you manually try to load it, then there must be an issue in pulseaudio as the transfer is done between the lightdm pulseaudio and the user pulseaudio, or something like that.

Since there are multiple people seeing this bug, and it seems very much related to pulse, I'm setting this bug to Triaged.

[Timo Verbrugghe (3-timo)]

Hi everyone!

This is the first time that I ever post anything on launchpad.net, so here goes!

I too am experiencing this bug, but I also noticed that this bug only happens on an x86_64 machine, not on an i386 machine.

Am using an intel NUC (64 bit install) and an old HP laptop (32 bit install) and a trust USB bluetooth dongle. On the HP laptop, module-bluetooth-discover is loading at startup. On the nuc side, I have to load it manually.

Hopefully this helps you to narrow down the problem.

Everything worked just fine in 13.10, before upgrade to 14.04.

[Hartwig Kolbe (kolbeb)]

It seems to work if the command
   pactl load-module module-bluetooth-discover
is executed directly after startup/login

But, then, don't use Blueman.

[David Henningsson (diwic)]

Hi Blueman developers,

This is an outreach for help - let me know if this is the right channel
or not. We seem to have a lot of people claiming that pulseaudio's
module-bluetooth-discover is not loaded on startup on 14.04. This causes
problems with bluetooth headsets.

Reading the code I can see that blueman deliberately unloads
module-bluetooth-discover. Do you have a better idea than just removing
those lines of code, which probably are there for a reason?

Here are some related bugs:

[Esko Kauppinen (esko-kauppinen-y)]

I have a Mint Mate 17.1 64 bit system which pairs the bluetooth HP mouse but it doesnt work.
From syslog:

[Jacek Kluza (jacek-kluza+ubuntu1)]

I fixed the issue simply by moving part:

.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif

...to the end of file (/etc/pulse/default.pa).
Hope it's working for you too. :)

[oldgranola (marken-john206)]

I tried Jacek Kluza's fix to no avail. Didn't work in Linux Mint 17.1 XFCE. I have a Linux Mint 17.1 Cinnamon desktop computer which uses 'cinnamon-bluetooth' applet instead of blueman which does work. I looked at bluez and pulse stuff and the default.pa file in that machine and compared to the one with blueman (with above problem requiring the manual modual load workaround). At the surface, all seems pretty much the same except the bluetooth controller cinnamon-bluetooth vs blueman. So I believe the problem is specific to blueman. BTW, to even get the missing module-bluetooth-discover to load from the command line, I had to un install the blueman which I had loaded via an application manager and install blueman from the command line.

[Jacek Kluza (jacek-kluza+ubuntu1)]

update: well... the fix with loading module-bluetooth-discover, as last module - works... just sometimes...

I added to startup:

pactl list modules | grep -q bluetooth-discover || pactl load-module module-bluetooth-discover

[Cristiano Fraga G. Nunes (cfgnunes)]

The problem is in "blueman-applet".

For more details, see:
https://github.com/blueman-project/blueman/issues/64

I solved the problem, installing the new version of this package (for Trusty), in:
ppa:cschramm/blueman

(https://launchpad.net/~cschramm/+archive/ubuntu/blueman)

[Ang Bongsong (notinsideofhereiamnotinside)]

Can confirm that this is currently occurring with pulseaudio 1:4.0 and the default Blueman package under Xubuntu 14.04.2 and Xfce 4.12.

Even though "load-module module-bluetooth-discover" is present by default in /etc/pulse/default.pa, it is not loaded at all on startup. It always must be manually loaded via entering "pactl load-module module-bluetooth-discover" in a terminal prompt, or running a script which does that on startup (after a roughly 8 second sleep period). Without the module loading at startup by default, it makes using devices like Bluetooth speakers a real hassle, and I strongly doubt the average user would be able to figure out an easy resolution to this issue.

P.S. Installing the newer Blueman package as mentioned in comment 20, does resolve the issue though, and I no longer need to have the aforementioned script run at startup.

[Luke Schlather (luke2760)]

The complete set of steps for the workaround are:

* In a terminal, run `pactl load-module module-bluetooth-discover`
* Right-click on the device in blueman, select "connect to audio sink"
* Open Puleseaudio volume control (pavucontrol), browse to "configuration" , use the dropdown to turn the Built-in audio profile "off"
* use the other dropdown to set the bluetooth device to use A2DP

I think the desirable behavior is you would hit "connect to audio sink" and audio would start flowing through the bluetooth device, and then if you hit disconnect it would start flowing through the default profile again.

However, there's an additional bug here, which is that after disconnecting (and manually switching the sink back on,) the default profile seems altered. I'm a little confused by what the underlying configuration change is, but xfce4-volumed can't control the volume of the built-in audio until I kill it and restart it:

killall xfce4-volumed
xfce4-volumed

[sparr (sparr0)]

This problem seems to persist in Xubuntu 15.04. The PPA mentioned in comment #20 does not have packages for vivid, only trusty.

[Cerin (chrisspen)]

After a recent update, Luke's solution no longer works for me. Trying to load the module just gives me an error:

    ~$ sudo pactl load-module module-bluetooth-discover
    Failure: Module initialization failed

and bluetooth never connects nor does any audio interface get registered. This is really frustrating. Bluetooth worked perfectly in 10/12 and now almost doesn't work at all in 14. How could this regress so badly?

[Chorca (chorca)]

Same issue here, I am unable to run the pactl load-module module-bluetooth-discover after some latest updates (over the past week). I verified the module is installed, and it is shown in a 'list modules', so should be loadable, but it refuses to load properly.

This issue has persisted through at least 3 released Ubuntu versions.

[ikedagus (ikedagus)]

I was able to have that fixed by disabling the Pulseaudio plug-in on blueman.

[rik kleinsmit (rkleinsmit)]

Ikedagus: what do you mean by "disabling the Pulseaudio plug-in on blueman"?

David Henningsson (diwic):
"Reading the code I can see that blueman deliberately unloads
module-bluetooth-discover. Do you have a better idea than just removing
those lines of code, which probably are there for a reason?"

Yes, you might ask the writers of blueman what the code is doing there and how to fix this. The writers are: Valmantas Palikša <email address hidden> and Tadas Dailyda <email address hidden>.

I think in the meantime, I will just remove those lines of code :-)

[Paula Thomas (paula11thomas)]

Xubunu version 14.04.1. Kernel 3.13.0-83-generic

This is most odd! Until yesterday afternoon the workaround of manually loading module-bluetooth-discover worked. Then it suddenly stopped and further attempts to load the module on reboot have been met with "ailure: Module initialisation failed" which is somewhat uninformative.

The following is an extract from syslog from my latest reboot I hope it is helpfull

I can also confirm that the solution mentioned at #20 works in xubuntu 14.04.4

[Luke Yelavich (themuso)]

We use bluez5 now since Xenial at least, and maybe even vivid. Check to make sure module-bluez5-discover is loaded.

[Jarno Suni (jarnos)]

Why isn't this SRUed in Trusty?

[Jarno Suni (jarnos)]

After installing the solution of #20:

In blueman: Devices..., search, Setup..., proceed without pairing, connect to A2DP Sink

$ pactl list modules short|grep bluetooth-device
29 module-bluetooth-device address="08:DF:1F:D9:93:80" path="/org/bluez/4093/hci0/dev_08_DF_1F_D9_93_80"
30 module-bluetooth-device address=08:DF:1F:D9:93:80 profile=a2dp

Oddly 2 devices.

[Jarno Suni (jarnos)]

Also, when using #20, bluetoothd crashes on startup.

[Adrian Merrill (metalchef)]

confirmed that the resolution posted by cfgnunes works on 14.04 LTS:

sudo apt-add-repository ppa:cschramm/blueman -y && sudo apt-get dist-upgrade -y

I'm using an MSi u-100 netbook with an upgraded intel 7260 network card; and I was going insane trying to get a2dp working. I no longer have to manually load the bluetooth module even though it was listed in /etc/pulse/default.pa.

Thanks!

[Sergio Arboleda (sergiogeek7)]

I got the same problem, Ubuntu 16.04.
When I run
-pactl load-module module-bluetooth-discover
Failure: Module initialization failed

and the file of answer 20 doesn not work either.

[fragargon (fragargon)]

I got the same problem today. Worked fine before problem started 2 days ago
(no more profile a2dp available through pulseAudio)

I reinstall bluez packages as pulseAudio-mudule-bluetooth, remove cinnamon-bluetooth and give a try with blueman.

I ran into the error "setup stream sound error" untill a manually launch pulseaudio-module-bluetooth.
So I remove the blueman and reiinstall cinnamon bluetooth (which depend on gnoma-bluetooth)
Since it connect as soon as I fireup my bluetooth headset senheizer HD 4.40BT
