Doesn't work on W10 20H2...tried all settings

[aecho-dev]

Hey,

I just tested the utility but cannot get it to work. I started it with the "inaudible sound" setting while the speakers were active. Then I waited a bit and the speakers turned off, even tho it was definitely running. While the speakers were still on standby I tried the "silence" setting but it didn't wake the speakers back up.

I tried stopping/restarting several times which doesn't work aswell. I thought that it's maybe sending to the wrong output device as I have built-in display speakers too but as there are no output settings I have no idea how to check which speaker the signal gets sent to.

Thanks in advance

Sound Keeper is a similar program, but it supports more signal types. You can try a low frequency sine, it should help in your case.
