Then you need to look in kde's system settings [...] phonon, and adjust the priority of the bluetooth sound device The bluetooth headset does not appear there. Only the internal soundcard is listed.

Once you set the priorities, as long as you don't delete devices (phonon will often warn and ask if it can delete if it doesn't see a device... one would hope it has logic to know not to do that with bluetooth devices since they're /expected/ to come and go, but I'm not sure...), when the device is the highest priority available, it will be what's chosen. But when it's not there but something with a lower priority is, it'll fallback to whatever it has available. So it actually is automated -- you don't have to do it ever time. If you don't see any bluetooth sound devices in that list, then it's probably not a kde problem, but a system/platform problem. That's really out of scope for this list, but I'm guessing it's what you're seeing. This. I don't think so, since the headset appears in KDE's bluetooth application and in SystemSettings - Network and connectivity - Bluetooth. Besides, I can pair and connect the headset successfully there. And here we hit the multiple layers problem. If kde's bluetooth app is seeing it, then you have base connectivity. But there's a problem between that and the phonon level, so it's not being seen in phonon. I'm running Kubuntu 12.04 x86_64. OK. Hopefully someone on kubuntu (either here or on their lists/forums, which I'm simply assuming they have, but most distros do) can fill in the missing pieces. I have a bluetooth keyboard + mouse kit (just one dongle for the two devices). They work perfectly. But this is another thing, because they do not use the bluetooth adapter embedded in the desktop, but their own provided bluetooth dongle, OK. That could possibly be used for troubleshooting, but that would be troubleshooting the bluetooth connectivity layer since it's a different device. And we now know the connectivity layer is fine -- the device shows up and can be paired at that level. So the troubleshooting at this level shouldn't be necessary. However, I can send files from the KDE desktop to my android devices using the embedded bluetooth adapter. That's QUITE useful, as now we know not only can it pair, but at least some devices are fully operational over it. Also mention whether /any/ apps, not just kde apps, play sound to the bluetooth headset or not. The common Firefox browser is gtk-based (Chrome/Chromium aren't kde based either, neither is Opera, all of which are browsers), for instance, so if it works with the bluetooth headset it may well be a kde problem. But if they don't work either, it's probably lower in the system. No application play sound to the bluetooth headset, Qt or GTK. System sounds are not played to the headset either. OK, seems the problem is most likely at the alsa or pulse-audio layer, since we know the connectivity layer works, but the device simply doesn't appear at the phonon layer, so it's gotta be in between and those are the major possibilities between. That's progress! =:^) But... FWIW, I don't use pulse-audio here at all, never have. And I strongly suspect that kubuntu's using it. So I'll be of little help there. Also, I don't actually use bluetooth here. So I'm of limited help in that regard, beyond narrowing down the layer as we just did. And finally, I'm a Gentooer, not a Kubuntuer (Kubunteer? Kubunter?). So I've probably provided all the help I can, personally. But knowing what we know now about the layers, someone else with better area-specific knowledge should be more effective at helping you now. The one other thing I can suggest, altho I don't know enough about bluetooth audio to be sure, is... I'd guess that you may still need the specific audio hardware kernel module loaded. Just like USB-audio needs both USB and the specific audio driver, so here I suspect you need both bluetooth (which does seem to be loaded and working) and the audio driver,
Re: [kde] How to use a bluetooth headset?
For what it is worth, on Kubuntu, fiddling with pulseaudio's settings can solve many sound devices issues. Try running `pavucontrol` and look for your devices. They may be here and disabled.

[kde] Wrap Firefox in KDE app?
I would like to use different icons for each Firefox profile. Firefox does not seem to support this, but all KDE applications support by default the --icon flag. Is there a simple way to wrap a launcher to a specific Firefox profile in a KDE application so that it might be possible to change the icon?

That's exactly the type of information I can't supply as I've never run pulse or kubuntu either one, that could very well solve the problem. Even if it doesn't solve it, verifying that the appropriate devices exist in pulse should further narrow down the layer at which the problem exists. -- Duncan - List replies preferred. No HTML msgs.

Firefox does not seem to support this, but all KDE applications support by default the --icon flag. Is there a simple way to wrap a launcher to a specific Firefox profile in a KDE application so that it might be possible to change the icon? Very interesting question! I don't know the answer for sure, but your question triggered a memory of a kde executable I'd seen, which looks quite promising. Please try the below and see if it does what you need, then report back, as you have me curious too, now. =:^) kstart [Qt-options] [KDE-options] [options] command Of course it has the usual kde-app --help, --help-kde --help-qt --help- all options, which you'd need to look at to see if it can do what you need. As I said a quick look looks promising, but you'll have to look closer than I did and probably actually try it, to be sure. The other alternative, which should work anywhere a *.desktop-based file is the basis for launching (including the kickoff apps menu and many icon- based launchers), /is/ a *.desktop file (or menu entry based on one). This has the advantage of being a freedesktop.org standard, so should work in DEs other than kde, as well, but won't work where *.desktop file isn't used. The key here would be to use firefox's -P profile option as the command, not simply firefox, and to set a custom icon as desired. You'd then clone that launcher item multiple times, changing the profile and icon for each one. I'd guess one or the other of these solutions should work. Maybe both, in which case you can take your pick. =:^) -- Duncan - List replies preferred. No HTML msgs. Every nonfree program has a lord, a master -- and if you use the program, he is your master.
