Supress playing a sound during start of the ESCAM PT202

[GqSteve]

Hi,

The ESCAM PT202 plays a sound, when the camera starts.

Is there a way to suppress this playback?

What sound?

[GqSteve]

There is a short sound of 3-4s playing, when the camera starts

Please, check which file it is:
audio_file.tgz

[GqSteve]

It is the common/poweron.aac sound file.

I see actually the problem as "whole"....when the camera is hidden somewhere, then another sound might be played...because the SD card is full. Would it be possible to remove the audio_file.tgz from the firmware (extract image, remove file, and recreate the firmware)?

These files are inside a read-only partition, so I can't delete them.
But I could "remove" overwriting with a mount bind command.
I don't know what's the behavior of the cam when it doesn't find a file or when the file is zero size and it's not possible to test all cases.
Try this file where I removed poweron.aac and let me know if the cam works and if it plays something.
Decompress it to /tmp/sd/yi-hack/script (rename previous file).
system.sh.gz

I will be able to test it in a couple of week and will give you a feedback asap. Thanks!
