Hmm. I went to check something online and there was an embedded youtube
video to see. I clicked on it and thought 'I know that tune!' :-) I had
forgotten that I'd left jack-play (not) playing and linked to the playback.
Paused the video and the music stopped. Un-pause and off it went again.
All wires shown dotted in Helvium, while paused.
Tried starting jack-play again with -t (jack transport aware). It said:
jack-play: a48k.wav
jack-play: seek request failed, 385225728 (That's beyond Eof)
jack_transport controls work while the video is playing, but do nothing
while the video is paused.
