When connected to external monitor, have to manually reset output device

When I plug my Macbook Pro into an external monitor, there is no sound whatsoever.

I fix this multiple times per day by opening the Sound menu in System Preferences, selecting "Internal Speakers (Built-in)", and then it snaps back to Boom2Device and the sound works.

If I quit Boom and repeat this, the sound works fine. 

I've been doing this manually multiple times per day for a few months since I purchased. Would love to see this bug fixed.


  • Hey,

    Could you please let us know your Mac configuration? Also, let us know the app version installed on your Mac.

    Please make sure that you have checked the option "Boom Helper" under Boom 2 Settings.
  • I've got this same issue, it's incredibly annoying.

    Running El Capitan 10.11.5 on a macbook pro mid 2014. Boom 2 version is 1.4.3, this issue has persisted through multiple updates, seems to be a macbook pro issue.

    Plugging in monitors/headphones etc all seem to kick the sound output from internal speakers over to Boom2Device. Only solution I've seen online was basically a terminal command to delete boom2, aka not ideal.

    Hope this can be resolved.

  • Hey,

    Please update your copy of Boom 2 to the latest version within the app itself. Also, you can download a trial copy of Boom 2 via our website www.globaldelight.com/boom next, register the same with the registration code provided to you on purchase.

    The Mac App Store version has also been released, please open your Mac App Store and check in updates column. 

  • Hi @KarthikNayak 

       I have same problem and I have Boom2 v1.5 MAC and I don't see anything newer?

       I have OS X El Capitan 10.11.6, MacBookPro (15inch, mid 2015), and two monitors plugged in via DisplayPort (Apple 27" LED Cinema, ASUS PB287Q).

       Every time I leave my laptop for awhile and the screens go to sleep, I come back and resume some video or audio and instead of going to my headphones it blasts the sound through my monitor at work which is very annoying.

        Is there a place to make Boom2 always use the same output device???
