Despite Audacity having failed to launch either from the terminal or

obviously needs guidance when opened. But I still don't know yet
whether the EZCap, or the Hauppauge for that matter, produces a
usable audio stream at all.


You should be able to investigate that with the arecord command as
outlined in earlier postings. First by using -l and -L to find its
card identification numbers or strings. Then by trying arecord with
-D followed by the relevant numbers/strings and reporting the details
of any errors returned by arecord.

As yet, though, I have no idea if the device you have will provide
audio in a format alsa can recognise.

Slainte,

Most of that we tried, and I got a silent recording, which led me to
agree with you that it probably doesn't provide a suitable format. At
the moment, I have a system that will record using the desktop's sound
card, and then I can just move the file over to the laptop for working
with Audacity. The laptop's location is much more comfortable than the
desktop's! But I will try again, just to be sure.
