Yes, you should be. It *will* affect recording. Make sure you are running
as root, lowlatency is enabled, and that jack is using a non-journaling
filesystem for shm. Make your latency as large as you can tolerate, in
fact I suggest choosing the -n and -p options as big as the device allows.
Make sure you don't have an autopoller checking the CD-rom drive.
I'm replying to a reply, so sorry if all these things were covered in
the parent.
