you can look here for a jack guide:

Didn't help, JACK just crashes after starting
Post the output of jack here and we'll go from there.
If you run alsa-info.sh from the command line and post the output it
will help us determine what hardware you are using

While we are troubleshoot, would be nice if someone can send me a wav
file of the D-flat pitch. That will at least get me started on my
arrangement. Cheers
thanks

While I look at the jack issue you can generate a tone through alsa/pulse
For Db you could try :
speaker-test -f 277.183 -t sine
This should work with pulseaudio running, otherwise you will have to
specify the card with the -D parameter
In your case this should work
pulseaudio -k; speaker-test -f 277.183 -t sine -Dhw:0
for me it is
pulseaudio -k; speaker-test -f 277.183 -t sine -Dplughw:0,0
For other octaves see
