Question Are there any PC apps for generating a continuous inaudible frequency sound?

[Aussie_Wolfhound]

I got a JBL Charge 4 speaker today to use as my PC speaker and it works great, except for one annoying thing... it auto shuts off after 15 minutes if not used. I googled this and there's no way to disable that, the only thing you can do is what the title says to keep it from turning off but I'm a tech noob so does anyone here know if there are any apps that do that?

Have you considered just playing music in the background(but with the volume on mute) off your device?

plug in DC power adapter

Maybe Task Scheduler could be used.....

Identify the process (or some process) that runs when the speaker is operating.

Then apply Task Scheduler to trigger that process when the process is found not to be running.

Task Scheduler has quite a number of features and functions that may be viable.

Triggers, Actions, Conditions, Settings, etc..

As for the process: Use Reliability History/Monitor and Event Viewer - either one or both tools may be logging that automatic shutoff.

Then you configure some task along the lines if "X" is off then turn "X" on.

I literally just learned about that... easy solution, Cheers.

In theory you can but definitely need some coding.

found someone have created AudioDeviceCmdlets powershell code

not good at powershell coding though

Plenty of apps out there.
Just search for tone or frequency generators.
Although the OP already found a better solution.

Also with a generator always be careful to stay within the specs of the speaker to avoid possible damage.

Tone or frequency generator definitely is easy to find, All OP needs to do is play that inaudible music file when the pc is on.

Indeed - there may be a number of viable solutions.

Key is to first discover the reason for the auto shutoffs.

Perhaps something else being stopped that, in turn, stops audio.....

I would use the link provided by@cruisetung and use the Get-AudioDevice cmdlet to obtain the available parameters and configurations.

Does not necessarily address the root cause for audio stopping but may provide some additional insight into what is happening.

Look (Get) first when audio is working.

Then again look (Get) again immediately after audio stops.

Determine, if possible, what changed.

Then use Set to restore the original setting. Is audio restored?

My starting point would be with "Playback......" settings.

Other cmdlets to help delve deeper: Get-Process, Get-PNPDevice.
