Streaming on Twitch is fun and rewarding, but nothing kills momentum faster than technical issues. Whether it’s audio that won’t sync, video lag, or dropped frames, these problems can frustrate both you and your viewers. The good news? Most Twitch streaming problems have straightforward fixes. Here’s a quick guide to the most common issues new (and even experienced) streamers face, and how to solve them.
1. Dropped Frames and Lag
The Problem: Your stream stutters or freezes while gameplay looks fine on your end. Viewers complain about lag, buffering, or pixelation.
Why It Happens: Dropped frames are usually caused by network issues, such as low upload speeds or unstable connections.
The Fix:
- Run a speed test—make sure your upload speed is at least 6 Mbps for 1080p, 3–5 Mbps for 720p.
- Lower your bitrate in OBS/Streamlabs. Start with 3500–4500 kbps for 720p.
- Use a wired Ethernet connection instead of Wi-Fi.
- Close unnecessary apps (like browsers, downloads, or Discord streams) to free bandwidth.
2. Audio Out of Sync
The Problem: Your mouth doesn’t match your words, or game audio lags behind visuals.
Why It Happens: Sync issues can stem from overloaded CPU, incorrect audio device settings, or capture card delays.
The Fix:
- In OBS, go to Advanced Audio Properties → adjust “Sync Offset” to manually sync.
- Ensure all devices (mic, webcam, capture card) are set to the same sample rate (48kHz recommended).
- Update sound card and capture card drivers.
3. No Game Sound (But Mic Works)
The Problem: Viewers hear your voice but not the gameplay.
The Fix:
- Double-check game audio is routed to the correct device (headphones vs. speakers).
- In OBS, make sure “Desktop Audio” is enabled and mapped to the right playback device.
- If using a capture card, select “Use custom audio device” and assign correctly.
4. Mic Too Quiet or Too Loud
The Problem: Viewers complain your mic is too soft, distorted, or peaking.
The Fix:
- Use OBS’s filters:
- Gain (to boost volume)
- Noise Suppression (to remove background hum)
- Limiter (to prevent clipping when you yell)
- Position your mic about 6–8 inches away from your mouth.
- Invest in a pop filter to cut harsh “p” and “s” sounds.
5. Black Screen When Capturing a Game
The Problem: OBS shows a black screen instead of your game window.
Why It Happens: GPU conflicts, especially on laptops with both integrated and dedicated graphics.
The Fix:
- Run OBS as Administrator.
- For laptops, assign OBS to the same GPU as the game in your graphics settings.
- Try switching between Game Capture, Window Capture, and Display Capture.
6. Webcam Not Showing
The Problem: Your camera doesn’t appear in OBS, or the feed is frozen.
The Fix:
- Make sure no other app (Zoom, Discord, etc.) is using the webcam.
- Deactivate and reactivate the webcam source in OBS.
- Check USB ports and update camera drivers.
7. Overheating and Stream Crashes
The Problem: Your PC overheats, causing OBS to crash or the stream to cut off.
The Fix:
- Lower your output resolution (720p is easier on hardware).
- Switch encoder to NVENC (NVIDIA GPUs) instead of CPU if available.
- Clean dust from your PC and improve airflow with fans.
8. Chat Not Showing in OBS
The Problem: You can’t see chat in your OBS overlay, making it hard to interact.
The Fix:
- Use Docked Panels in OBS: View → Docks → Custom Browser Docks → paste Twitch chat link.
- Alternatively, use tools like StreamElements or Streamlabs Chat Overlay for an in-stream chat box.
9. Stream Delay (Latency Issues)
The Problem: Your stream has a long delay, making viewer interaction awkward.
The Fix:
- In Twitch Dashboard → Settings → Stream, enable “Low Latency Mode.”
- Lower bitrate slightly if your internet is unstable.
- Avoid unnecessary background uploads (cloud backups, torrents, etc.).
10. Alerts Not Working
The Problem: Follower or subscriber alerts don’t appear on stream.
The Fix:
- Test alerts in Streamlabs/StreamElements to confirm they’re connected.
- Ensure your Browser Source in OBS is at the top of the source list.
- Refresh the widget URL in OBS if it stops working.
11. Echo and Feedback Issues
The Problem: Viewers complain about echo or doubled audio.
The Fix:
- Mute your stream preview tab in Twitch.
- Check if both “Desktop Audio” and “Game Capture” are capturing game sound (disable duplicates).
- Use headphones instead of speakers to avoid mic feedback.
12. Poor Stream Quality Despite Good Internet
The Problem: You have fast internet, but your stream still looks pixelated.
The Fix:
- Check CPU/GPU usage… your hardware may be the bottleneck.
- Lower your output resolution to 720p for smoother streams.
- Use CBR encoding with recommended bitrates:
- 720p @ 60fps → 3500–5000 kbps
- 1080p @ 60fps → 6000 kbps
13. OBS Crashing on Startup
The Problem: OBS refuses to launch or crashes right away.
The Fix:
- Update OBS to the latest version.
- Update your GPU drivers.
- Disable third-party overlays (Discord, NVIDIA Shadowplay).
14. Twitch Stream Key Not Working
The Problem: OBS can’t connect to Twitch because of a bad stream key.
The Fix:
- Reset your stream key in the Twitch Dashboard → Settings → Stream.
- Copy and paste carefully into OBS (no extra spaces).
- Make sure two-factor authentication is enabled on Twitch.
15. Overcomplicating Your Setup Too Early
The Problem: New streamers often install too many plugins, overlays, and bots at once, causing instability.
The Fix:
- Start simple with just OBS, a webcam, and one chatbot.
- Add new tools gradually as you get comfortable.
- Test changes offline before going live.
