Disable power off/on sound

[Guest Raul6]

I have looked in

\HKEY_CURRENT_USER\ControlPanel\Sounds\

and few other places but couldn't see where is the poweroff_tmo referenced. Where do i go to remove it?

If you mean sound that played as part of start-up animation, you may have difficulty, since this is more part of bootloader than usual OS.

that probably explains why i couldn't find it in registry. Any workarounds? That sound is too loud and annoying every time i do a soft reset.

The only solution I can think of is to get a hold of wav file which does not contain any sound, rename it to poweron.wav and poweroff.wav and dump it in the \Windows\ I tried deleting or renaming the original file, but the system just restores it so hopefully tricking the system would work.

If anyone manages to try it out, hope you will update this thread.

[Guest Raul6]

in addition to renaming/deleting i thought of editing the existing sound file making it quieter but if OS does a crc or other check then it is all academic. I'll try renaming first when i have a moment

To get rid off of the 'sound annoyance' you need to have a file explorer which is able to overwrite existing system files (Resco File Explorer for example).

The steps to follow:

1) copy silence.wav from \windows directory to, say, your SD card (silence.wav is system file and hidden)

2) rename this copied silence.wav to PowerOn.wav

3) repeat 1) or copy PowerOn.wav from 2) to your SD card (or where ever you want to)

4) rename this file to PowerOff.wav

5) copy these both newly created files PowerOn.wav and PowerOff.wav into \windows directory (remember: these are system files which aren't allowed to be overwritten per default, and are hidden files. So use something like Resco File Explorer, etc.)

And another thing to remember:

after every hard reset (not soft reset) these files are generated again, so you have to repeat the steps above again.

To add to the steps above. I created a blank wav, so just copy it to your \Windows\ and if you want, create a copy and rename to poweroff.wav

I have tried it and it works fine, no more irritating tone ;)

poweron.wav

Thank you all. I have also replaced poweron_tmo and poweroff_tmo (although i made backup just in case) with silence.wav using inbuilt file explorer showing all files. The sweet, sweet sound of silence ;)

[Guest Massive Attack]

why make it quiet? if we can replace it, ill replace it with another sound like a ringtone, maybe a nokia sound ;)

[Guest Raul6]

if we can replace it, ill replace it

Go for it, can do being the operative word ;)
