I know how frustrating it is when you’re trying to enjoy your favorite show and the sound keeps dropping out. You’re not alone – soundbar audio cutting out is one of the most common home theater problems in 2025. The good news is that most fixes take just a few minutes and don’t require any technical expertise.
Problem Summary
When your TV soundbar cuts out every few minutes, it’s usually caused by connection issues, power-saving settings, or interference from other devices. This problem affects your viewing experience and can make dialogue impossible to follow, but it’s almost always fixable without replacing any equipment.
Step-by-Step Fixes
Step 1: Power Cycle Everything (2 minutes)
Turn off your TV and soundbar completely. Unplug both devices from the wall for 30 seconds. This isn’t just turning them off with the remote – physically disconnect the power cables. Plug the soundbar back in first, wait for it to fully boot up, then plug in your TV. This simple reset clears temporary glitches that cause audio dropouts.
Step 2: Check Your HDMI or Audio Cable (3 minutes)
Gently wiggle the cable connecting your soundbar to your TV. If the sound cuts in and out when you move it, you’ve found your problem. Try unplugging and firmly reconnecting the cable at both ends. If you’re using HDMI ARC, make sure you’re plugged into the port labeled “ARC” or “eARC” on both devices. For optical cables, check that the protective caps are removed and the cable isn’t bent sharply.
Step 3: Adjust Your TV’s Audio Settings (5 minutes)
Navigate to your TV’s audio settings menu. Look for options like “Digital Audio Output” or “Audio Format.” Change the setting from “Auto” to “PCM” or “Stereo.” Many newer TVs default to advanced formats like Dolby Atmos that some soundbars can’t process consistently. Samsung TVs often have this under Settings > Sound > Expert Settings. LG TVs place it in Settings > All Settings > Sound > Digital Sound Output.
Step 4: Disable Power Saving Features (3 minutes)
Both your TV and soundbar might have eco-mode or auto-standby features that cause audio interruptions. On your soundbar, look for settings like “Auto Power Down” or “Eco Mode” and turn them off. Check your TV for similar options under General Settings or Eco Settings. Vizio soundbars are particularly known for aggressive power-saving modes that need adjustment.
Step 5: Update Firmware on Both Devices (10 minutes)
Outdated software causes compatibility issues between your TV and soundbar. For your TV, go to Settings > Support > Software Update. Most soundbars update through their companion apps – download the official app for your brand (Bose Music, Sonos, Samsung SmartThings) and follow the update prompts. This fix is ideal for solving persistent dropout issues.
Step 6: Switch Connection Methods (15 minutes)
If nothing else works, try a different connection type. Currently using HDMI? Switch to optical. Using Bluetooth? Try a wired connection instead. Each method has different strengths – HDMI ARC is best used in setups with newer equipment, while optical connections are ideal for older soundbar models. Bluetooth is not recommended when you need consistent, uninterrupted audio.
Likely Causes
Cause #1: HDMI Handshake Issues
Modern HDMI connections constantly communicate between devices to verify copyright protection and audio formats. When this “handshake” fails, your audio drops out temporarily. You’ll notice this happens more when switching between apps or channels. Check for it by watching if dropouts occur during content changes. Fix it by using high-speed HDMI cables (version 2.1 ideal for 2025 equipment) and ensuring CEC settings match on both devices.
Cause #2: Wi-Fi and Bluetooth Interference
Your soundbar’s wireless signals compete with routers, phones, and smart home devices operating on the same frequencies. This is especially problematic in apartments or homes with many wireless devices. Test for interference by turning off nearby devices temporarily. If the dropouts stop, relocate your router further from your entertainment center or switch your soundbar to a wired connection.
Cause #3: Overheating
Soundbars generate heat, and poor ventilation causes internal components to throttle performance. Feel the top and back of your soundbar after it’s been running for 30 minutes. If it’s hot to the touch, overheating might trigger protective shutdowns. Ensure at least 4 inches of clearance around all sides and never place objects on top of the soundbar.
When to Call Expert Help
Contact professional support when you’ve tried all these steps and audio still cuts out regularly. If your soundbar is under warranty, call the manufacturer first – they often provide free troubleshooting. Local TV repair shops can diagnose hardware failures for $50-100. Consider replacement if your soundbar is over 5 years old and repair costs exceed $150, as newer models have better compatibility with current TVs.
