Cannot hear from “HEADPHONE

    Just after updating to PROFILER Operating System 8.5.8.30570, I cannot hear from HEADPHONE.
    Confirmed Kenper receiving guitar signal (can tune by Kemper, can see the signal).


    Any suggestion how to fix?

    I only can use headphone at my apartment, it is critical for me.

    thanks for your response.
    could you let me know a bit detail “perform the Init Globals reset on the foirst page of the system menu”.

    I just can not find where is the “foist page”.
