Issue: Digital burst over MADI

Postby JReiser » Fri Apr 06, 2018 8:01 am

Hi There,

I experienced some issues today using LP2 over Madi with an AVID S6L.

I had intermittent bursts of noise down all my Madi channels. It seemed like the LP2 was falling over as after this burst of noise there was no input to any of my chains. If i restarted the audio device in audio and Midi options i would have audio ip/op again. (restart meaning changed any settings, or enable/disable use more threads, also restarting LP2 solved this issue for a few minutes before it happening again.

I'm running at 96k with a buffer size of 512samples. my DSP meter is in the 20 -30% range with use more threads and 50-60% without.

MacBook Pro (Retina, 15-inch, Mid 2015)
2.5 GHz Intel Core i7
16 GB 1600 MHz DDR3
Plenty of free disk space

I use this setup regularly and havent had any issues like this before, however not sure if i've used LP2 over madi since i've updated to 2.1.5 mainly using it with a KT DN9630 Usb to AES50, or over dante with a CL5.

Any help much appreciated, worst case i can go over analogue for the show but not ideal

To others:
This issue is being handled via email.
Best bet is that it is the USB audio in OSX 10.11 bug.
Will report back when we know more
