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
