How can we improve Adobe Audition?

← Audition

Hardware compatibility - MOTU M2 & Audition 13.0.13 - Stuttering playback Mac OSX

Latest version of Audition 13.0.13 caused stuttering playback using a MOTU M2 device. Playback was normal using internal audio device. I reinstalled 13.0.10 and playback was normal. I went back a few versions. I didn't try 13.0.11 or 13.0.12. I believe that the issue was introduced in 13.0.13.

    The screen shot doesn't show anything out of the ordinary. Neither does the other included info.
    Can you try disabling the input by setting it to No Input and see if that helps or not?

    And, do you have any digital connections to the M2 at all via the ADAT or SPDIF ports?

    I don't know what is wrong so I'm asking general question trying to determine if there is a smoking gun or not.
