Hi everybody,

I am new on the forum, here is my problem.
I have Kodi krypton installed (via Noobs) on a Raspberry pi 3, the whole is connected to a video projector by an HDMI cable, and I would like the sound sort of my hi-fi, located at 2 M to break everything .
The problem is that I have a huge gap between the sound and the image, I can not manage at all!
Sorry it's a google translation, I'm french
thank you in advance for your help

I am no expert, and maybe your exact meaning didn't make it through the translator, but...

You could introduce the following into the audio chain:
1) a Bluetooth transmitter supporting the AptX Low-Latency codec
2) Either a Bluetooth headset supporting the AptX Low-Latency codec OR a Bluetooth receiver supporting the same codec. You would then plug a wired headset into that receiver.

There are Bluetooth devices that can be either a transmitter or a receiver. You select the mode with a switch.

If your project has audio-out you could use that, or you could use the analog output on the Pi.
