Audacity won't start (Ubuntu 16.10) error

Hi all,

This is my first post here, I really hope that you can help! I have ducked and googled, but could not find a solution to the problem I’m experiencing. I am not a super technical linux user, has to be said as well.

I strongly suspect that since I updated from Ubuntu 16.04 LTS to 16.10 audacity won’t start anymore. The icon flashes and then stops, and nothing happens. I tried uninstalling and reinstalling in the Software Centre, but no different result. Then I tried uninstalling, and then installing via the ubuntuhandbook PPA http://ubuntuhandbook.org/index.php/tag/audacity/. Still the same result. When I try starting it from a terminal typing:

audacity

and hitting enter it gives as only output:

audacity: symbol lookup error: audacity: undefined symbol: PaAlsa_GetStreamInputCard

I don’t know what it means. If you do, and could walk me through a solution, please enlighten me! :slight_smile: And perhaps more people using Ubuntu 16.10 are struggling…

Cheers, sirdude

Have you self-compiled PortAudio or some application that uses it, or installed a new audio application since installing 16.10?

What does this return?

ldd /usr/bin/audacity | grep portaudio

If it returns /usr/lib/ then I would report it to Ubuntu because it looks like a system problem.

Also if you updated to Ubuntu 16.10 over 16.04 this could be the reason. This isn’t a reliable way of updating. Try installing 16.10 fresh.

Hi Gale,

Thanks for your reply! I updated the system to 17.04 a few days ago, and the error is still the same. I did install OpenFrameworks and Android libraries, but not sure if that was the reason it doesn’t work. I just tried your suggested input, and got:

libportaudio.so.2 => /usr/local/lib/libportaudio.so.2 (0x00007fd875d3f000)

Going from this, what would you say I should do?

Best,
Wouter

An Audacity package installation in /usr/ should not be pointing to portaudio in usr/local/lib. That local portaudio seems to be the problem.

I assume you could mess up your optional applications if you interfere with the local portaudio, so try launching Audacity from the terminal thus:

LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity

If that works you can adjust the “Exec” line in your Audacity.desktop file (presumably in /usr/share/applications/ ) with that line so that you don’t need to use the Terminal to launch Audacity.


Gale

Hi Gale,
Thanks for the tip! When i type in the terminal:

LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity

Then it returns:

And it opens a workable Audacity! When i close Audacity it returns this:

** (audacity:2897): CRITICAL **: os_bar_hide: assertion 'OS_IS_BAR (bar)' failed

(audacity:2897): Gtk-CRITICAL **: IA__gtk_widget_hide: assertion 'GTK_IS_WIDGET (widget)' failed

** (audacity:2897): CRITICAL **: os_bar_set_parent: assertion 'OS_IS_BAR (bar)' failed

So basically the problem is solved, except for the Audacity.desktop file. I used sudo nano to change the exec line to:

LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity

But it then doesnt find the file anymore afterwards. I don’t know what the exact syntax is for the exec line (tried looking up exec key and stuff, but it was of a bit too deep level for me to understand).
This is the audacity.desktop file content normally:

I would be even more happy if you could give me advice on how to change the exec line :slight_smile:
Thanks in advance!

sirdude

What do these commands give you?

dpkg -s audacity



apt-cache showpkg audacity

and same for the package libportaudio2

Yes, that is listed as a bug in the 2.1.3 Release Notes.

You need to add the path command, not replace the original text with it.

I would guess this would work:

Exec=env UBUNTU_MENUPROXY=0 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity %F

If it doesn’t, please ask on the Ubuntu forums.


Gale

Hi Gale and steve,

The exec line in the audacity.desktop file that you suggested works like a charm:

Exec=env UBUNTU_MENUPROXY=0 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity %F

Thank you so much!

Description: Portable audio I/O - shared library
 PortAudio is a portable audio I/O library designed for cross-platform
 support of audio. It uses a callback mechanism to request audio
 processing.  Audio can be generated in various formats, including 32
 bit floating point, and will be converted to the native format
 internally.

Please do tell me if you find anything that could be of interest to me in there, because my audio when using the plug (ALSA) is not in very good shape. But perhaps that is something for the regular Ubuntu forum. :slight_smile:

Thanks again for the support!

Cheers, sirdude

Hi Gale (and others),

See my former post about the problem now being solved. There is however one thing I would like to add for your information. The first thing Gale asked me on this thread came to mind, and at the time it did not seem to be a direct cause to the problem, so I did not mention it. But now I’m adding just for the complete picture. Gale asked me this:

Have you self-compiled PortAudio or some application that uses it, or installed a new audio application since installing 16.10?

I answered that I had installed OpenFrameworks and some libraries. What I didn’t mention was that I had/have been working with PureData (visual programming language and IDE for sound).

So, just for completion. Perhaps it is useful in the future (who could possibly into the same problem when having PureData installed).

Cheers, sirdude

Thanks for the feedback.
I don’t see anything obviously wrong from the information that you have posted, so although we can see what was going wrong, it’s a mystery to me ‘why’ it was going wrong. Anyhow, glad that you have a usable workaround.
