Occasional playback noise with Ardour + Delta-66
Hello, my setup is a Dell Dimension 9150 with a dual-core 2.8GHz Pentium D, 2GB RAM, 160 GB SATA disk, and an M-Audio Delta-66 audio I/O card.
Software is: Jack 1.103, Ardour 2.0.2 (home-compiled version) on 64-bit SuSE 10.2.
In the simplest case, my problem manifests itself when playing back a single track. I don't know the professional term for the kind of noise I'm hearing, but it's like, perhaps, dropping grains of sand on a paper surface, superimposed on the audio.
I get no xruns, load is almost nil, nothing indicates overload.
Sometimes it helps to stop, then play again. At other times, I have to quit Ardour and start over.
I've seen this some 10 times over the span of a couple months; 9 of which was with Ardour, one with Sooperlooper.
