Soundbar Standby Blocker


European directive dictates electronic devices have to go into standby mode after certain period of inactivity, usually 15 minutes of not playing anything to save power. Such behavior can be annoying when soundbar is used as output on computer where there might not be sound event for extended periods of time, but we want device to be ready when any sound does get played.


Soundbar Standby Blocker is a tiny program that tricks soundbar (or any speaker with such power saving mechanism) from going into power saving standby mode by playing a specially crafted 3 seconds long 10Hz tone every 10 minutes. It should be entirely inaudible to the user at normal volume levels, but will nudge the standby sense on the soundbar and make it think it just had to play a sound, causing it to reset the internal standby timer. Soundbar will stay on and ready to play any sound for as long as Soundbar Standby Blocker is running on the computer.


  • Soundbar Standby Blocker will not work if computer volume is set too low or is set to mute.
  • It may prevent computer from going into standby under certain conditions.
  • File “tone.wav” must be present in same folder as Soundbar Standby Blocker program, otherwise it will not function. User can replace it with own audio sample, but must retain same name and same audio format (WAV).
  • Tone played in 10 minute intervals will be captured along with all other sounds if you’re for example performing a gameplay capture on your computer while Soundbar Standby Blocker is running. Technically it shouldn’t be audible, but you’ve been warned about potential interference.

  1. Thank you so much for this…is there a way to make this a startup item so I don’t have to run this every time I start up?


  2. Hi thank you for this, it’s perfect. Just one thing, where do I store the downloaded file?
    If I install and move the file to another drive the app will not run.
    I don’t want it on the desktop.
    Sorry for silly question but I’m old.
    Thank you


    1. App requires no installation, just place it somewhere (including the WAV file next to it!). As far as “Start with Windows” function goes, if you activated it and then moved the EXE file, the startup entry isn’t pointing to correct location anymore. Just turn the feature of and on again. It’ll refresh the startup entry to new location. That’s it 🙂


    1. Unfortunately I haven’t quite figured out yet how to design this because I want to keep the portability design and pair it with ability to adjust the looping cycle. At the moment I basically just made different builds, I might just do that for now.


  3. Please is this workable when using a flash drive to play music with the sound bar.

    Is there a way the flash drive can play the wave file to keep the sound bar active from standby

    T for Thanks


  4. Hey RejZoR,
    I just want to say you are a legend for making this. I used the 10 second special edition version you linked below, and it works like a charm. My issue is that the soundbar cuts out within 1 second of not receiving loud enough audio. So during things like podcasts the soundbar cuts out when there is a pause. All I know is that your thing made it better. My JVC soundbars probs stuffed but it is what it is.
    I did want to ask: is there a way for you to make a 3-second edition so that there is constant audio to my soundbar and it doesn’t shut off. While the 10 second works, if the time aligns wrongly ill still get the issue.

    I do want to say thank you again for all your work so far!


    1. Jesus christ, what idiot thought “yes, we should make our device go into standby in just few seconds of no sound”. I still have ancient set of Altec Lansing MX5021 PC speakers that can be on forever and won’t turn off, but after hearing horror stories of speakers going into standby and trying to “upgrade” to soundbar speaker for my PC I created this app. I just never thought companies actually make such dumb designs that standby goes into effect of just seconds of no use. It’s like they never even use their products to think that’s even remotely acceptable behavior.

      Seeing this, I may just create one that has continuous never ending loop, sort of like a constant hiss or white noise. Hm.


      1. Yeah it’s ridiculous! All I want to say is thank you so much for all your work. You’re actually amazing! Do you have a Discord?
