Program Crash: Reports Nyquist Files Missing

/usr/bin/audacity

In that case you should have a folder:
/user/share/audacity/

/user/share/audacity/

Now we're getting somewhere!
In alphabetical order my user/share folders jump from:

/usr/share/audacious
to
/usr/share/autoconf

[steve]

Try running this command - it will take a while as it searches your entire computer:

Code: Select all

find / -type d -name "nyquist" 2> /dev/null

[NorfolkGreg]

Unfortunately, absolutely nothing!

Code: Select all

[email protected] ~ $     find / -type d -name "nyquist" 2> /dev/null
[email protected] ~ $ 

this search also made me realise that my NAS doesn't hold it as I only backup my "greg" user folder.
Another Linux lesson learned!

I've had an idea.
Try installing "audacity-data"
and then try launching Audacity and see if you still get the message about missing Nyquist files.
and run the "find / -type d -name "nyquist" 2> /dev/null" command again.

I have tried un-installing and reinstalling the program

How exactly are you doing that?

Simply by using Mint's Software Manager.

Is that a GUI application? What's the exact name of Mint's Software Manager? If it has "Help > About", or "About" anywhere in it, what does it say?

[NorfolkGreg]

Try installing "audacity-data"

The Software Manager installs audacity-data as a dependent package when you opt to install Audacity.

and then try launching Audacity and see if you still get the message about missing Nyquist files.
and run the "find / -type d -name "nyquist" 2> /dev/null" command again.

and I get the empty result.

Here's the initial screen, with Help>About:

And here's what it shows when I search for "audacity" and the View is set to show both "Installed" and "Available" packages.

It has worked without issues for me as a naive user up till now. (The green ticks indicate installed packages.)

Mint also provides the Synaptic Package Manager, which has a lot more technical detail about the package installed, and I have only used once when wanting to install a package direct from a publisher. I see that has both an "Mark for Removal" and "Mark for Complete Removal" options.

As I said at the beginning of the topic I fear that my issue started after a power cut and wonder if files/folders got corrupted/deleted as a result of that. Evidence suggests that the "Software Manager" only "disables" an application when it uninstalls it and performs a "recovery" of the original installation when reinstalled - and in my case that is corrupt.

Is using the Synaptic Package Manager to do a "complete removal" followed by an "install" would overcome the issue?

Try that.
It certainly appears that parts of Audacity are missing.

As I said at the beginning of the topic I fear that my issue started after a power cut and wonder if files/folders got corrupted/deleted as a result of that.

It's rather worrying if that is the case, because who knows what else may have been corrupted? Loss of power "shouldn't" be able to do that (though loss of power can corrupt files that are being written to at the time of the power loss, but that shouldn't be the case here).

Hi Steve,

Apologies for the long delay. Christmas got in the way!

So I tried the Package Manager. Initially it complained that things were not in order and asked me to fix that and then happily did a complete uninstall. I've re-installed Audacity (using the "Software Manager") The Nyquist folder is back and the "High Pass Filter" (and other) options are back on a "Plug-ins 1-12" sub-menu of "Effects", so it appears all is well again.

(Still have no realistic theory on why it all went wrong. I agree with you that my idea that it happened as a result of a power cut is far fetched.)

Many thanks for your help.

Well, it's been a year since I was last here, and once again I have suffering what I described it last year...

9 times out of ten playback of a file occurs at "quadruple speed" with just "static" coming from the speakers. If I then attempt to stop play complete lockup of the program occurs, with the "Stop" button remaining depressed. An attempt to close the window causes a delay before a "Marco" dialogue appears:

However, this time there are no missing Nyquist files! I read through the topic and early on there was a reference to

There should normally be a "(hw:0\0)" item in the playback settings (in the device toolbar), but you don't currently have that, probably because something else is still using the sound card.

Suddenly, it dawned on me! Last year I was continually running a copy of Jacquie Lawson's Advent Calendar throughout December in a browser window! I am this year too, but didn't get my copy till 22 December - and it was after that I launched Audacity and started having the problem.

I've just closed the Calendar and all is back to normal. I still don't know how I lost the Nyquist files last year, but I do now know why I got "quadruple speed static".

Thanks, Steve, for all that help last year. It's still coming in useful a year on!
