Hmm, when I try, xlinrad runs fine. For hours.
Do you see "No input" in the lower left corner with a number
that slowly increases?

I did find an error though, when I click a signal Linrad exits
with an arithmetic error. When restarting I am prompted for
new parameters because the output sampling speed is zero and that
is not permitted. After I have given it a value (e.g.11025) I see no
problems. Use U in the main menu to select a soundcard. Then
press Z to ignore it. I will correct this. Thanks for pointing
me to another bug:-)

Maybe you are not running as root? For reasons unknown to me
SDR-14 does not work here when I am logged in as a normal user.
It does run fine with sudo however.

Maybe someone can tell me what to do to make the SDR-14/SDR-IQ
run without root privileges???
(Look at the bottom of Makefile to see how things are done now.)
