Jack and base noise level
Posted: Wed Aug 15, 2018 10:29 am
Hi folks,
I've struggling with futility to get a decent DAW recording, midi sequencing external setup going. My DAW of choice has been Bitiwig1.3 but it's pretty ropey when it comes to sequencing outboard gear. I've been testing Tracktion 7 and it seems very usable however now I'm having audio issues. I generally like to stay away from Jack as I always get in a mess between that, pulseaudio and ordinary apps and I never use VST's or ITB routing anyway.
However, testing audio with Tracktion set to ALSA has really bad crackling through it which doesn't happen with Jack. So I'm happy to run with Jack for the time being. But when I enable Jack2 I get a base level hiss/whine/noise which stops the instant I disable Jack. I've checking patching and there aren't any silly things like mic's routed to output or anything. It's present on all sample rates and buffer sizes and is constant whether I'm recording, playing back or anything.
I've tested with a Behringer USB mixer and a Fasttrack Pro. Same symptoms on both.
What else can I check? Are there configs I could post to help?
