To connect an AV receiver (AVR) to your PC, run an HDMI cable from your graphics card's HDMI output to one of the receiver's HDMI inputs, then set the receiver as your default audio device in Windows. If your receiver is older and doesn't have HDMI, you can use an optical (TOSLINK) cable, a coaxial digital cable, or analog RCA cables from your PC's audio output instead. Once connected, wire your speakers to the receiver's binding posts, matching channels and polarity.
That's the short version. Below, we'll walk through every step in detail, including what an AV receiver actually is, why pairing one with your computer is one of the biggest audio upgrades you can make, and exactly how to hook everything up whether your receiver is brand new or twenty years old.
What is an AV receiver (AVR)? An AV receiver , short for audio/video receiver , is the central hub of a home theater system. It performs three jobs at once:
Switching: It accepts audio and video signals from multiple sources (PC, game console, Blu-ray player, streaming box) and routes them to your display and speakers.Processing: It decodes audio formats like Dolby Digital, DTS, Dolby Atmos, and multichannel PCM, splitting the signal into separate channels for surround sound.Amplification: It powers your speakers directly, with far more clean wattage than any motherboard audio jack or soundbar can deliver.Think of it as a traffic controller, translator, and power plant for your entertainment setup, all in one box.
Why connect an AV receiver to a PC? If you already own an AVR, or you've spotted one cheap at a thrift store, connecting it to your computer unlocks serious benefits:
Dramatically better sound quality. A receiver driving real bookshelf or tower speakers will outperform virtually any desktop speakers or gaming headset at the same price.True surround sound for gaming and movies. Modern receivers decode 5.1, 7.1, and Dolby Atmos, so games and films sound the way they were mixed to sound.More power and volume headroom. Receivers typically deliver 70 to 150 watts per channel, which means clean, distortion-free sound even at high volumes.One hub for everything. Plug your PC, console, and streaming devices into the receiver and switch between them with one remote.A second life for older gear. Even a 15-year-old stereo receiver can turn your PC into a genuinely impressive music system.In short: if you care about how your games, movies, and music sound, an AVR is the single biggest upgrade path available to a desktop PC user.
What you'll need before you start A desktop or laptop PC with an available video or audio output (HDMI, DisplayPort, USB-C, optical, or a 3.5 mm headphone jack) An AV receiver (any era; we cover both HDMI and legacy models below) The right cable for your connection type (HDMI, TOSLINK optical, coaxial, or 3.5 mm-to-RCA) Speakers and speaker wire (14- or 16-gauge wire works for most rooms) 15 to 30 minutes Method 1: connect a PC to an AV receiver with HDMI (newer receivers)
HDMI is the best way to connect a modern receiver to your PC. A single cable carries lossless multichannel audio and video, supports every surround format including Dolby Atmos, and requires almost no configuration.
Step 1: find the HDMI output on your PC Desktop: Use the HDMI port on your graphics card (the ports near the bottom of the case, oriented horizontally), not the motherboard's HDMI port, if you have a dedicated GPU.Laptop: Use the built-in HDMI port, or a USB-C to HDMI adapter if your laptop only has USB-C/Thunderbolt ports.Step 2: connect the HDMI cable to the receiver Plug the cable into any HDMI IN port on the back of the receiver. Many receivers label inputs (Game, PC, BD, CBL/SAT), but the labels are just names, so any input works. Note which one you used.
Step 3: connect the receiver to your monitor or TV
Run a second HDMI cable from the receiver's HDMI OUT (ARC/eARC) port to your monitor or TV. The receiver passes the video through while handling the audio itself.
Tip for high-refresh gamers: Older receivers may limit pass-through to 4K/60 Hz. If your receiver can't pass your monitor's full resolution or refresh rate, connect your monitor directly to a second output on your graphics card and use the receiver for audio only. Windows lets you send audio to the HDMI output even if no display is using it for video.
Step 4: select the input on the receiver Power on the receiver and use the input selector to choose the HDMI input you plugged your PC into.
Step 5: set the receiver as your audio device
On Windows 11:
Right-click the speaker icon in the taskbar and choose Sound settings . Under Output , select your receiver (it usually appears by its brand name, e.g., "Denon AVR" or "NVIDIA High Definition Audio"). Click Sound Control Panel → Playback , right-click the receiver, and choose Configure Speakers to set 5.1 or 7.1 and test each channel. Step 6: test it Play a video or run the Windows speaker test. If you hear sound from every speaker, you're done.
Method 2: connect a PC to an older AV receiver without HDMI Receivers made before roughly 2006 often lack HDMI entirely, but they can still sound fantastic. You have three options, listed from best to most universal.
Option A: optical (TOSLINK), best for surround sound
Many PCs and motherboards include an optical S/PDIF output (a small square port, often with a flip-up door that glows red).
Connect a TOSLINK optical cable from the PC's optical output to the receiver's OPTICAL IN . Select the matching input on the receiver. In Windows Sound settings, set the digital output (often labeled "Digital Audio (S/PDIF)") as your default device. For surround sound in games, open the device's Properties → Supported Formats and enable Dolby Digital and DTS, then enable encoding (Dolby Digital Live or DTS Connect) in your sound card's control panel if available. Limitation: Optical carries uncompressed stereo or compressed 5.1 (Dolby Digital/DTS), but not lossless formats like Dolby TrueHD or Atmos.
No optical port on your PC? A USB-to-optical adapter (often sold as a "USB sound card with S/PDIF") costs little and works on both desktops and laptops.
Option B: coaxial digital, same quality as optical
Some PCs and receivers use a coaxial S/PDIF connection (a single orange RCA jack) instead of optical. It carries the identical digital signal. Just follow the optical steps with a 75-ohm coaxial cable instead.
Option C: analog RCA, works with any receiver ever made
This is the universal fallback, and for music it can sound excellent.
Get a 3.5 mm to stereo RCA cable (one headphone-style plug on one end, red and white plugs on the other). Plug the 3.5 mm end into your PC's headphone/line-out jack (the green port on a desktop). Plug the red and white RCA plugs into any analog input on the receiver. CD , AUX , or TAPE IN all work. (Avoid the PHONO input; it's specially amplified for turntables and will sound distorted and far too loud.) Select that input on the receiver and set your PC's volume to about 80 to 90%, controlling final volume with the receiver knob. Limitation: Analog RCA from a headphone jack is stereo only. For surround on a non-HDMI receiver with 5.1 multichannel analog inputs , you'd need a sound card with matching 5.1 analog outputs and three 3.5 mm-to-RCA cables. It's a niche but workable setup for enthusiasts.
How to connect speakers to your AV receiver With the PC side handled, the final step is wiring your speakers to the receiver.
Step 1: plan your layout 2.0 / 2.1 (stereo): Front left + front right, optional subwoofer. Perfect for desks.5.1 surround: Front left/right, center, two surrounds, subwoofer.7.1 and beyond: Adds rear surrounds (and height channels for Atmos).Step 2: cut and strip your speaker wire Cut a length of 14- or 16-gauge speaker wire for each speaker, leaving slack. Strip about 1 cm (3/8") of insulation from both ends of each conductor and twist the bare copper strands tight.
Step 3: mind the polarity Every speaker connection has a positive (+, usually red) and negative (−, usually black) terminal. Speaker wire is marked to tell the two conductors apart with a stripe, ribbing, or copper vs. silver coloring.
Connect + to + and − to −, on both the receiver and the speaker. Reversed polarity won't damage anything, but it puts the speaker "out of phase," which hollows out the bass and smears the stereo image.
Step 4: connect each speaker to its matching terminal On the back of the receiver you'll find labeled terminal pairs: FRONT L, FRONT R, CENTER, SURROUND L, SURROUND R , and so on.
Binding posts: Unscrew the cap, insert the bare wire through the hole in the post, and screw the cap down snugly. (Banana plugs make this even easier if your posts accept them.)Spring clips: Press the tab, insert the wire, and release.Make sure no stray copper strands touch the neighboring terminal. A single whisker bridging + and − can trigger the receiver's protection mode or damage the amplifier.
Step 5: connect the subwoofer Powered subwoofers use a single RCA cable from the receiver's SUB OUT / LFE jack to the subwoofer's LFE IN . Plug the sub into wall power and set its crossover dial to max or "LFE" (the receiver will manage the crossover).
Step 6: run the receiver's setup Modern receivers include automatic room calibration (Audyssey, YPAO, MCACC, Dirac). Plug in the included microphone, place it at ear height in your listening position, and run the routine. On older receivers, set speaker sizes, distances, and levels manually in the setup menu, or just balance levels by ear with the test tone.
Troubleshooting: no sound from the receiver? Check the default audio device. Windows loves to switch outputs after updates or reboots. Right-click the speaker icon → Sound settings → confirm the receiver is selected.Check the receiver input. The most common culprit: the receiver is simply set to the wrong source.HDMI shows video but no audio? In Windows Sound settings, the display's audio device may be selected instead of the receiver's. Choose the entry that names your receiver.Receiver disappears when the PC sleeps? This is normal HDMI behavior. Disabling "allow the computer to turn off this device" in Device Manager for the GPU audio device can help.Hum or buzz on analog connections? Usually a ground loop. Try plugging the PC and receiver into the same wall outlet or power strip.One speaker silent? Swap the speaker wire to a known-working channel to isolate whether the issue is the speaker, the wire, or the receiver channel.The bottom line Connecting an AV receiver to your PC takes one cable and a few settings changes, but the payoff is huge. Instead of relying on small desktop speakers or a headset, you get real amplification, real speakers, and real surround sound for games, movies, music, and streaming. Use HDMI if your receiver supports it, or use optical, coaxial, or RCA if you are connecting to an older receiver. Once your speakers are wired correctly and your receiver is calibrated, your PC can become the center of a full entertainment setup.
That setup works best when the computer behind it is just as capable as the audio system. A powerful receiver and speaker setup can make games and movies feel more immersive, but the PC still has to handle the heavy lifting: running modern games smoothly, pushing high-resolution visuals, managing surround sound output, streaming media, and keeping background apps from slowing everything down.
For that kind of setup, the Acer Nitro 60 Gaming Desktop is a strong match. It comes with Windows 11 Home, an Intel® Core™ Ultra 5 processor 225F, NVIDIA® GeForce® RTX 5060 graphics, 16 GB of DDR5 memory, and a 2 TB PCIe® 4.0 NVMe™ SSD. That gives you the performance headroom for modern PC gaming, high-resolution entertainment, fast loading, and smooth multitasking.
It also includes Wi-Fi 6, Gigabit Ethernet, and Bluetooth 5.3, making it easier to connect online, stream content, use wireless accessories, and keep your gaming or media setup flexible. Pair the Nitro 60 with a capable AV receiver and proper speakers, and your desktop is no longer just a computer. It becomes the core of a high-performance gaming and home theater system.
Frequently asked questions Can I connect my PC to an AV receiver without HDMI?
Yes. Use an optical (TOSLINK) or coaxial digital cable for surround-capable digital audio, or a 3.5 mm-to-RCA analog cable for stereo. Both work with receivers that predate HDMI, and USB adapters can add an optical output to any PC that lacks one.
Does connecting through a receiver add input lag for gaming?
HDMI pass-through adds a few milliseconds at most on modern receivers, which is imperceptible for nearly all gamers. If you're chasing every millisecond or need a refresh rate the receiver can't pass through, connect your monitor directly to the GPU and use the receiver for audio only.
Can I get Dolby Atmos from my PC?
Yes, over HDMI to an Atmos-capable receiver. Enable Dolby Atmos in Windows under Sound settings → Spatial audio (the Dolby Access app handles licensing for some configurations). Optical and analog connections cannot carry Atmos.
Can a laptop connect to an AV receiver?
Absolutely. Use the laptop's HDMI port, a USB-C-to-HDMI adapter, the headphone jack with a 3.5 mm-to-RCA cable, or a USB audio interface with optical out. The steps are identical to a desktop.
What speaker wire gauge should I use?
16-gauge is fine for runs under about 15 m (50 ft); use 14-gauge for longer runs or low-impedance (4-ohm) speakers. Thicker wire never hurts — it just costs slightly more.
Is an old stereo receiver from the 1990s still worth using with a PC?
Often, yes. Vintage receivers frequently have robust amplifier sections that drive bookshelf speakers beautifully. Connect via the analog RCA method and you've got a high-quality desktop music system for the price of one cable.
