Re: Sound specialists,help appreciated.
Cannot say much, but ... is jack indeed started before you try ardour? An item
can be placed in env to do this automatically if you so choose.
Audacity does NOT require jack, however. Plays just fine for me.
So ... check your alsa configuration. Typing cat /proc/asound/cards should
yield a list of active devices and lsmod should also show stuff. If alsa is
not working, jack, of course will not either.
