What version of Ardour are you using and can you describe your computer
setup a bit (hardware, audio interface, OS/version, etc)? How many tracks
are you trying to record and play back at a time, and at what bitrate and
Do you see any error messages from JACK or qjackctl (if you started JACK
that way) about xruns or warnings about your disk(s) not being able to
keep up with the amount of data you need to move? If you're precording or
playing back multiple tracks, does the popping/hissing go away at all if
you run fewer simultaneous tracks? Note that just muting a track won't
reduce your I/O load - you need to temporarily disable the tracks you
don't need to use at the time.
