Why Isn’t My Windows PC Giving Surround Sound on My TV with eARC?

So your Windows PC’s surround sound isn’t getting through to your TV via eARC? That’s no fun, but I’ve got some tips that might help get things back on track.

First up, let’s talk cables and connections. You want to make sure those HDMI cables are snug-fitting and top-notch. Look for ones marked “High Speed with Ethernet” or “Ultra High Speed”—they’re worth it. Double-check if your cables are up to snuff for eARC.

Next, dive into your TV’s settings. You want eARC or ARC switched on. Not sure where? Have a poke around in the audio settings—it might be stashed away under “Advanced Settings” or “Audio Output.”

Over on your PC, right-click on that speaker icon in the system tray, and pull up “Sounds.” Head to the “Playback” tab and set the HDMI output device (probably labeled with the TV or AV receiver) as default. Once you’ve done that, tweak the properties under the “Advanced” tab for high def audio—something like 24-bit, 48000 Hz should work nicely. Just keep an eye on those virtual surround settings in the “Enhancements” tab—bin them if they’re there!

Keeping things updated is another piece of this puzzle. From your graphics card and audio driver right down to your TV and soundbar firmware, it can all be a game-changer if there are compatibility gremlins.

What about surround sound formats? Make sure they’re turned on, like Dolby Digital or DTS. Don’t forget to check your TV for surround sound pass-through capability.

And here’s a heads-up: not all media flexes surround sound muscles. Grab some tried-and-tested files with surround sound to check if it’s all working.

A couple more things while I’m at it: switch off your TV’s internal speakers—they can mess with the setup. Also ensure your PC is kicking out surround sound and not reverting to stereo. Flick through your user manuals for some extra compatibility tips—couldn’t hurt!

Stick with these steps, and you might find yourself back in surround sound bliss soon. If things still aren’t jiving, maybe the support docs for your gear have got more tricks up their sleeves.

What’s Up with Your Surround Sound?

So, you’re dealing with the surround sound saga, huh? If your Windows PC continues to be a silent partner in this setup from your TV to the receiver using eARC, it’s time to dive into the nitty-gritty. With all the gizmos involved, a little tinkering might work wonders.

First Up: Let’s Talk Hardware

1. Graphics Card: Got yourself an NVIDIA RTX 4070? Sweet! This baby supports HDMI 2.1, which means you’re set for the fancy sound formats like Dolby Atmos.

2. TV: That LG C2 from 2022? It’s got eARC ready to rock on its HDMI ports, letting you beam some serious sound back to that fancy receiver.

3. Receiver: Your Denon X2400H might not be a spring chicken when it comes to HDMI 2.1, but it’s got eARC in its bag of tricks. Make sure you’re plugged into the right HDMI output from your TV.

Get Those Connections Right

• Pick up some legit HDMI cables, preferably those rated for HDMI 2.1, to make sure no bits and bytes fall through the cracks.

• A quick glance over those cables might save your sanity—everything in its right place, snug and secure.

Time to Tweak Windows Settings

1. Tuning Your Windows Sound:

   • Take a stroll down to the system tray, right-click on that speaker icon, and dive into “Sounds.”

   • Under “Playback,” make sure the TV’s the star of the show as your default playback device.

   • Fancy a surround dance? Click “Configure” and pick out “5.1 Surround” if lady luck shines on you.

2. Don’t Forget Dolby:

   • If Dolby Atmos is in the house, double-check it’s geared up within your settings.

   • Flip open the app and see if it’s in cahoots with your audio output device for the Atmos shenanigans.

Time for TV Settings Shenanigans

• On your LG C2:

  • Hit Settings > Sound > Advanced Settings.

  • Opt for “Pass Through” or “Auto” under Digital Sound Out—say goodbye to other formats for now.

  • Make sure eARC is living its best life—enabled and ready.

Let’s Handle the Receiver

• On your Denon X2400H:

  • Get it tuned to receive the sweet audio vibes via HDMI from your TV.

  • Look for ARC/eARC settings in the menu. Flip the switch to ‘on’ if you spot them.

Trial by Testing

• Test your mettle with different sources:

  • Streaming from apps on your LG C2—Netflix or Amazon Prime, for example? If the surround works there but not from the PC, you’ve got some PC tweaking ahead.

Do all this, and if surround sound remains elusive, perhaps some fresh cables or firmware updates will pave the way to audio bliss. You know how these techie gadgets can be a little stubborn sometimes.

To wrap it up, getting surround sound from Windows PC through your LG C2 TV then to your Denon X2400H with eARC is all about connecting the dots with compatible gear, tweaking those settings, and a dash of patience. You got this!
