Strange sound TBM 900

[cromsan]

Even when the engine is not running I hear strange sound

It appears it's linked to the COM volume.  Just turn it off on the audio panel.  Can you confirm if the crash bar is up or down?

[cromsan]

Goran, I put 0 the Com volume on the PFD, and the crash bar is up, but the noise continue.

[Goran_M]

The COM radio is on the essential bus.  Meaning if the crash bar is up, it will provide power to the radios and the left PFD.  Pull the crash bar down and the sound should stop.

Goran, I have the strange sound also with the crash bar down. It only happen recently on the TBM900, not in other aircraft.

I just tested this myself.  I am unable to reproduce it.  I even pushed the crash bar up, pressed the buttons on the audio panel, and still nothing.  My essential bus avionics turn on with the crash bar up, but no radio static.  

Do you have any kind of avionics hardware, scripts, external 3rd party ambient atmospheric add ons, etc... that could be causing this?  Anything at all??  No matter how insignificant you might think it is.

Goran, at this moment the strange sound have dissapear. If it appears again, I will send you, as you say,  any kind of avionics hardware, scripts, external 3rd party ambient atmospheric add ons, etc.

 

Thank you,

[cromsan]

Goran, the strange noise appears again, with the crash bar up.

I can not send my log.txt.

Goran, sorry, and thank you, problem resolve. I have ON button NAV 1, without putting  frecuency in active Nav 1 of nearest VOR LEVS, to hear the morse code.
