HDMI sound issue : "ploc" on reading

Hello,

My LE8-Odroid C2 is connected to my TV using HDMI cable, then optical from my TV to my DAC.

WIth this setup, I can hear "ploc" a the beginning of a media reading ( movie or music), then a second "ploc" few seconds after the end .

"ploc" is a sound. a very brief sound but at a high level of volume. (pop?).

the problem sounds like a relay activation to enable sound output? Do you have any idea on how to disable this sound?

I didn't face this issue with all my others devices that are connected the same way one my tv.

I'm hearing that sound too when enabling stereo upmix. So I left it disabled

thanks foryour help modig

The stereo upmix is already disabled.

I've change system settings/audio : "keep audio divice alive"=always
When i activate/change this option, i can hear the pop each time..
