Uncover The Audio Secret: Lg Tv’S Pcm Vs Auto Digital Sound Output

When connecting your LG TV to an external sound system, you’ll encounter two options for digital sound output: PCM and Auto. Understanding the differences between these settings is crucial to optimize your audio experience.

What is Digital Sound Out?

Digital Sound Out (DSO) is a feature that allows you to transmit audio signals from your TV to an external audio device, such as a soundbar, home theater system, or headphones. It provides a higher quality audio experience than traditional analog connections.

PCM vs. Auto: The Key Differences

PCM (Pulse-Code Modulation) is a digital audio format that encodes analog audio signals as a series of binary numbers. It preserves the original audio quality without any compression.

Auto is a setting that automatically selects the best digital sound output format based on the capabilities of your TV and the connected audio device. It typically chooses PCM when possible, but may switch to other formats if necessary.

Advantages and Disadvantages of PCM

Advantages:

• Preserves the original audio quality without any loss
• Supports high-resolution audio formats

Disadvantages:

• May not be compatible with all audio devices
• Can require high bandwidth, potentially leading to delays or dropouts

Advantages and Disadvantages of Auto

Advantages:

• Automatically selects the best output format for your setup
• Ensures compatibility with most audio devices
• Reduces the risk of audio delays or dropouts

Disadvantages:

• May not always choose the highest quality audio format
• Can be less predictable than PCM

Which Setting Should You Choose?

The best setting for you depends on your specific setup and preferences.

Choose PCM if:

• You have a high-quality audio device that supports PCM
• You want to ensure the highest possible audio quality
• You’re not experiencing any audio delays or dropouts

Choose Auto if:

• You’re not sure which format your audio device supports
• You want a hassle-free setup with minimal configuration
• You’re experiencing audio delays or dropouts with PCM

How to Change the Digital Sound Out Setting

To change the digital sound out setting on your LG TV:

1. Go to Settings > **Sound** > **Advanced Settings**
2. Under Digital Sound Output, select either **PCM** or **Auto**

Troubleshooting Audio Issues

If you’re experiencing audio issues with either PCM or Auto, try the following troubleshooting steps:

• Check that your audio device is properly connected to your TV
• Make sure that your TV and audio device are both set to the same digital sound output format
• Try restarting both your TV and audio device
• Update the firmware on your TV and audio device
• Contact LG customer support for assistance

Takeaways: Optimizing Your Audio Experience

Understanding the differences between PCM and Auto for digital sound out on LG TVs is essential for optimizing your audio experience. By choosing the right setting for your setup, you can enjoy high-quality sound and minimize any potential issues.

Information You Need to Know
