HDMI audio is not working (Laptop is connected to LG TV via hdmi)

displaylinkuser · 04-07-2020, 06:35 AM

Hi,
I've a docking station.
I've connected my lg tv to the docking station via hdmi cable.
Docking station is connected to asus laptop.

I can display my PC screen via the TV,
I can not see the LG TV as a playback device and I can use the TV speaker,
even if I look deep in audio playback devices of windows 10 - Not there.
If I connect the HDMI cable directly to the laptop - I can see the LG TV as a playback device and get audio from the TV.
It's strange, because in the past it worked,
It stopped working since I replaced the HDMI cable to longer one - since then it's not working.

Hello,

Can you tell me what is the length of the new cable?

Best regards,

I've a 20 meters HDMI cable

Is it a problem?

I remind that the TV audio works perfectly when the HDMI is connected directly to the laptop and TV.

Hi,

The length of the new cable should be okay.
When you are connected through the dock to the TV do you see the TV showing in the Sound settings -> Output devices? Or does it not show at all?

Best regards,
Katarzyna

It is not showing.

The LG-TV audio device shows and works properly only if I connect the HDMI directly to the laptop from the LG TV.

If I connect the hdmi cable to the docking station then I won't see the LG-TV audio as a playback device at all, even if I enable and display the disables devices.

(windows 10 / Laptop asus)

What do you think is the issue?
