Closing this bug as it works for me (Xubuntu 20.04) and we've not seen any reports of this problem for many years.

Everything in terms of audio devices is managed quite well with pulseaudio, bluetooth-applet, and other Gnome desktop infrastructure. It tries to hard and breaks it. It tries to hack into my bluetooth in a vain attempt to find a headset or something like that and it ruins my bluetooth support in the desktop. I am no longer able to send files or use bluetooth in anyway. First thing it does when you launch it is that it does nothing. It'll just hang. You click on the icon in the menu and you won't get any feedback. Even if you run it from the command line it will give no feedback and display no errors. It just hangs. Then you kill it and restart it a couple times and it launches successfully. Sorta. Besides the globalmenu bug reported in another report it displays this error on my terminal: $ audacity bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3653 Here is the errors reported by dmesg: [ 807.086761] EXT4-fs (dm-0): re-mounted.

After hitting ctrl-f to work around the globalmenu bug (even though I am not using global menu) I can then edit files and such. Save them. Everything works. Of course I can no longer connect to the internet through my phone, send files, upload ringtones, use my bluetooth headset, etc. To work around you can remove the USB bluetooth adapter if you use a external one, plug it back in, and launch bluetooth-applet from the command line and it should be working again. It's not the end of the world, but Audacity should be configured to work properly in the default environment. I suggest eliminating Alsa and bluetooth support and have it not try to fight proper daemons handle it as they do a much better job. At least with PA and Bluetooth. I don't know how well Jack supports bluetooth audio devices, but Audacity really should not be allowed to do this sort of thing. I understand that it seems like a nice feature to be able to use a headset outside of Gnome, but it seems to be fundamentally incompatible with having a bluetooth adapter that is able to work with any other device. For people that may run into this problem in the future through Google or whatever here is two work arounds I suggest: 1. Remove or otherwise disable all your bluetooth radio prior to attempting to run Audacity. 2. If you forget to do that and Audacity breaks your ability to use bluetooth then remove the bluetooth audio device from your computer, plug it back in, and either log out/log in or start bluetooth-applet manually from the command line or 'alt-f2'. If your using internal bluetooth then try turning it off and on. If that fails then you will be forced to reboot. Thank you for your time and your patience. Keep in mind that as long as this bug exists you will probably have people complaining that either Audacity won't launch or will try to file bug reports against the kernel or bluetooth support in Gnome. It's not obvious that this problem is caused by Audacity's bluetooth support unless you run it from the command line. So most people are probably not going to make a connection that one is breaking the other. If your lucky you might be able to wipe out a couple other bug reports. Information on what I have installed: $ dpkg -S `which audacity` audacity: /usr/bin/audacity $ dpkg-query -s audacity Package: audacity Status: install ok installed Priority: optional Section: sound Installed-Size: 7376 Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com> Architecture: amd64 Version: 1.3.12-7 $ lsusb|grep -i blue Bus 006 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) $ uname -a Linux ubunturox 2.6.35-23-generic #41-Ubuntu SMP Wed Nov 24 11:55:36 UTC 2010 x86_64 GNU/Linux $ lsb_release -rd Description: Ubuntu 10.10 Release: 10.10 What I expected to happen: Open Audacity to edit a file for a ringtone. Make a quick edit, save the file, upload to the phone via bluetooth What happened instead: Audacity hung 2 or 3 times and finally opened. Made a quick edit to a mp3 file for a ringtone. Tried to upload the file to the phone via nautilus 'send to' support, and eventually realized that Audacity broke it. A final suggestion for Ubuntu: I don't know how to do it but applications should have all Alsa access disabled except through PA. None of these apps should have access to hardware to do things like this... they should go through services provided by the desktop. I have a sinking suspicion that Ekiga is another application that is breaking my hardware by trying to be too clever. I have a USB headset and Bluetooth headset that have been screwed up by my Linux laptop. They worked fine out of the box with no configuration and no effort. Everything was able to read from their microphones and play music and audio through them via PulseAudio, however after playing around with SIP both developed bad configuration problems. Keep in mind that I used them both for a very long time and the only thing that I can think they had in common was that I struggled to get Ekiga working with the microphone due to it's lack of proper audio configuration support. I think that it went and tried to 'optimize' things to make the microphone work, but ended up doing weird things by using low-level alsa features in unusual ways. I don't know this for a fact and I can't reproduce it, so filing a bug is probably a waste of my time. I was able to recover my bluetooth headset back into a working configuration after letting it's battery drain, but I still can't get my USB headset working again (it seems to be stuck into weird in-between mode between stereo and mono. Stereo sounds play find, but sounds that come out equally in both left and right seem to cancel each other out and are very quiet and echo-y). Again, thank you for taking the time to read this. Linux audio has come a long long way from the days of having to grep through /proc/asound files to find the proper values to put into my dmix asoundrc configuration to make movie playback non-suck.
