/etc/bluetooth/audio.conf file is removed in 2013, but blueman still tries to write it and fails.

Steps to reproduce:

Start blueman-applet.
Right-click on tray icon, choose "Local Services...".
Check both checkboxes in Audio tab.
Click Apply.
Exception throws while trying to parse non-existing /etc/bluetooth/audio.conf:

^C

As a result, I can't enable audio features in blueman.

I'm on bluez 5.27, blueman 1.98_p20150105 on Gentoo.

In Audio.py blueman is adding / removing values Sink, Source, and Gateway to / from the General section of audio.conf. At a quick look I could not find a way to do this now (starting with 5.8). Do you know?

gentoo-root · 2015-02-04T15:42:04Z

I'm sorry, but unfortunately I never worked with bluez directly, so I don't know a way to fix this.

gentoo-root · 2015-02-04T15:47:21Z

If you modify audio.conf to setup a2dp audio sink functionality, you may take a look at KDE's bluedevil sources, it has such functionality and does not modify audio.conf.

cschramm · 2015-02-04T16:03:08Z

Thanks, I'll have a look.

cschramm · 2015-02-05T13:13:25Z

I cannot find such a setting in the bluedevil GUI. Can you point me to that?

gentoo-root · 2015-02-05T14:42:35Z

There are two ways of doing it. Of course, you need bluedevil and pulseaudio running. Let's suppose there are two paired and trusted devices - Android phone named "Tru Phone" and my KDE laptop named "ideapad".

The first way is initiating connection from phone.
Go to bluetooth menu on phone and press gear icon near ideapad:

Tick the checkbox near "Multimedia sound" ("Звук мультимедиа"):

Connection will be established immediately, pulseaudio loopback appears:

The second way is initiating connection from laptop.
Go to bluedevil's menu and press "Connect" in device's submenu:

Connection will be established immediately, pulseaudio loopback also appears.

These two ways are fully equvalent and lead to the same results. Second way is just less intuitive - it's not obvious that Connect button will establish a2dp audio connection.

P.S. Sorry for Russian screenshots, I hope you will understand what's going on anyway (by icons and by items placement). If you won't understand something, I can translate text or try to make English screenshots.

cschramm · 2015-02-05T15:59:51Z

The second way should work in blueman as well. The notebook is connecting to an audio service of the phone. It should work independent of the settings in "Local services". The fact that this process is unintuitive is - unfortunately - a design concept of BlueZ 5 (see this thread if interested).

I'm not sure what's going on in your first example, specifically if you're connecting to a service provided by the notebook or somehow triggering the notebook to connect to the same service of the phone as in the other process (this would be odd as I don't no a way to do such a "reverse connect"). Do you see the same things on the phone when trying this with blueman?

The most obvious explanation is that BlueZ provides an audio service by default and bluedevil does not do anything there. This is also the way it should work in blueman. The only additional feature blueman has (or had) is re-configuring BlueZ to enable and disable those services. It's just an extra so to say and if they are always enabled or enabled by default the easiest solution is to just remove the "Audio" tab from the "Local settings" dialog. If there is a new way to enable / disable the BlueZ features, the user then just needs to do it directly at the BlueZ level instead.

I've just tried to test a2dp audio sink feature with blueman on gentoo, and it worked! No configuration needed, so that checkbox in blueman settings is useless now. Before that, I only tried to test this feature on xubuntu 14.04 livecd, and it was very buggy. Maybe it's xubuntu-specific bugs, because on gentoo Advanced Audio Receiver with blueman works like a charm, so the corresponding checkbox in blueman settings dialog should be removed, and blueman should not try to modify audio.conf to enable this feature as it's enabled by default.

There is also second checkbox named "Headset Emulation" in blueman settings dialog, and I was unable to test this feature. When I pair my phone with xubuntu, I get two checkboxes in my phone's settings - one for multimedia sound, and one for in-call sound. And when I pair my phone with gentoo, I only get one checkbox for multimedia sound. I was unable to test Headset Emulation, because xubuntu is very buggy (it even can't connect in Advanced Audio Receiver mode), and my gentoo just don't expose such feature. Could you please tell me what should I turn on in bluez or/and pulseaudio settings so that Headset Emulation on my gentoo appears?

gentoo-root · 2015-02-06T01:36:56Z

OK, I've managed to set up both A2DP and HSP/HFP profiles on gentoo using bluez5, ofono, pulseaudio and blueman. "Audio" tab in "Local Services" menu of blueman is no longer needed to get things working - they are working out of box if necessary software is installed. So I think usage of Audio.py and Audio tab in blueman settings could be safely removed if blueman is targeting new versions of bluez.

cschramm · 2015-02-06T07:11:12Z

In my opinion it's also not necessary for older versions of BlueZ. The user can at least modify the audio.conf file himself. So I will just remove that.

audio.conf does not exist in BlueZ 5.8 and higher. The services should work without enabling them specifically. See #174. Also remove iniparse library, BluezConfig class, and Config mechanism plugin. :) Closes #174 Closes #175

Created a PR. Nice cleanup. 😼
