There is a bug in Pulseaudio that is stopping pa from releasing the audio

device.
The temporary solution until it is fixed and released is to disable

autospawn and restart pa.
edit ~/.pulse/client.conf
add
    autospawn = no
restart pulse with
    pulseaudio -k

    pulseaudio -D
or maybe with
    pasuspender -- jackd
If that fails you may need to completely kill pulse or just restart the

machine to get it to release the audio device. Once you have disabled

autospawn it should only need to be done once and only if you have already

been using pulse to listen to a some audio.
