How to Fix No Video After Switching HDMI Ports but Audio Works

🔹 Problem Overview

• Devices involved: HDMI Switch + Audio System + Display Device

• Issue:

  • Port 1 is connected to the audio system

  • Switching from Port 1 to another port causes no video display

  • Audio system works normally

🔧 Step 1: Return to Port 1

• Switch the HDMI switch back to Port 1

• Wait 10-30 seconds for the audio system to complete initialization

⚡ Step 2: Switch to Other Ports

• After the audio system is fully initialized, switch to other ports

💡 Tip:

• This is a normal behavior due to the HDMI switch waiting for audio system initialization

• Always allow the audio system to finish initialization before switching ports to avoid temporary video loss
