YPAD feed does have audio but its verrrry quiet so crank your speakers all the way up.
I'm currently working on rectifying this issue. It is a result of a new server & location resulting in 50m audio cable running from the scanner to the $2 usb soundcard.
Thanks for your patience.
EDIT: Have got the feed temporarily running on an old laptop, appears to be a soundcard issue rather than length of cable. Will order a new usb soundcard.
