Not having interrupts would have a dramatic impact on sound quality - no sound! The ehci hardware will generate interrupts one per ms. I'm not sure if these get double counted or if there is actually two per ms, but the linux kernel doesn't change the default interrupt threshold which is to rate limit interrupts to one per ms. I'm completely missing the assertion that interrupts will impact sound quality though - this is cpu activity necessary to make the device work. ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
