USB connected QC has input delay.

Quad Cortex Bug Reports
1

CorOS Version: 2.3.0

Describe your issue:
When I use my QC connected via USB to my MacBook Pro in Logic Pro (input QC/output Scarlet 2i2).
After some time of playing (or not playing, just don’t do anything for 5-10 minutes), QC starts giving me the response signal with a 2-3 seconds delay which makes it impossible to play. Only a reboot can fix it. Really afraid to catch this one during the live show.

Steps to reproduce your issue:

  1. Turn on QC & open LogicPro
  2. Play a bit & put the guitar down for 5-10 minutes.
  3. Have the signal from the guitar 2-3 seconds later.

I expected this to happen:
When I stop playing for some time, I can catch the bug.

I have tried the following things:

  • I have tried changing settings in LogicPro
  • I have tried updating the QC

Is your Logic Project set to 48kHz?
Have you tried making an aggregate device from your interfaces?

It was 44kHz by default, after changing to 48kHz there are no any issues.
Thanks!
