Hi all,

In further bizarre behavior, if I type the command rosegarden in a
terminal, rosegarden comes up but NOT in superuser mode, if I then import
a rg file, it seems to come up normally which contrasts that if I mouse
click on an rg file it brings up rosegarden in superuser mode!

In any event, in either mode I get the message "audio subsystem not
available - can't record audio" from Rosegarden.

However, I can record into Audacity, but then how do I synchronize it if I
do several tracks at different times, i.e. not everything in one go?

Thanks again for looking into this,
