I just tried to open Audacity on my laptop, and it fails, and of

I get:

`snd_pcm_format_linear(slv-format)' failed. Aborted"

I think I'll stop there, unless this means something to somebody! I
did the Reset Preferences procedure as described in the Wiki, but it
made no difference.

It certainly means something to Google, though what it means seems to
be something to do with the JACK audio subsystem which I have never
used. If it still means nothing to you then perhaps uninstalling
anything JACK-related may be a good idea.

Indeed. I have no idea what Jack is, but it is there, in /usr/lib64.
But what happens otherwise if I remove it?

Linux audio has so many different systems anyway that removing ones
you don't need can only help (says the man who once again has given up
with PulseAudio and uninstalled it, although this time Pulse lasted as
much as 14 months before getting its automagic settings into such an
irrecoverable twist that it was no longer usable).
