That looks like something is using that device.
run
aplay -l and look for the ALSA name of the device you are using
run
pactl list module short
Identify the module by the ALSA name
then
pactl unload-module < module number >
Also when starting jackd try using hw:<ALSA NAME> instead of a number
when your system starts your audio devices will not always have the same device
number, BUT they will always have the same ALSA name.
see below
