Hi, I wonder if this is normal... I get a lot of noise - clicks and pops - when connecting Jack ports. The noise appears when I run Jack in duplex mode and with a period size less than 2048 frames. I get no noise if I run Jack with playback only. If I for example run Hydrogen and connect its ouput ports to alsa_pcm playback ports I get noise when in duplex mode but no noise when in playback only. The strange thing is that I get no xruns when the noise appears. I do not run out of CPU power either - the CPU usage is down to about 10% when running Jack and one client for example. What I want to do is to record 24-bit audio with my Emagic Emi 6|2m USB audio box. I can do this at the moment - the captured audio is clean and I can use the hardware monitoring to monitor what is being captured. Naturally I would like to get rid of the noise as well to take full advantage of what the box should be capable of. I could simply run Jack with 24-bit capture and with a period size of 2048 or more but Jack refuses to start with such settings. Should I just accept the situation as a fact or is there something I could do to get rid of the noise when running Jack in duplex mode and with 24-bit samples? The Kernel I am using is a 2.4.25, Alsa is 1.0.3 and Jack is 0.94 all from from PlanetCCRMA. The hardware should be irrelevant - the same problem appears in 3 different computers I have tried ranging from a Celeron 700 to a P4 2.4 Ghz. Ideas, anyone? Br, -Jorma __ Sano ei kuukausimaksuille.
