How to troubleshoot common audio and video issues in Skype business calls

If you’ve ever been in a business call where your voice sounds like a robot, or your video freezes on the least-flattering frame possible, you’re not alone. Skype meetings are supposed to “just work,” but the real world is messier. This guide is for anyone who needs to fix common audio or video problems in Skype calls, fast—whether you’re the tech-savvy one everyone turns to, or just want to stop yelling “Can you hear me now?” every five minutes.


1. Check the Basics Before You Panic

Let’s not overthink it—most Skype issues come down to a handful of boring but fixable things.

  • Is your device plugged in and not muted?
  • Did you join the right call? (Don’t laugh. It happens.)
  • Are your headphones or webcam actually connected?
  • Is your internet working for everything else?

If anything here isn’t right, fix it first. It’s amazing how many “tech problems” are just unplugged cables or muted mics.


2. Test and Configure Your Devices

Skype (link here) can only work with what it sees. If your audio or video isn’t working, make sure Skype actually knows which device to use.

For Audio Issues

a) Check Microphone and Speakers

  1. Go to Skype Settings:
  2. Click your profile picture.
  3. Select Settings > Audio & Video.
  4. See what’s selected under “Microphone” and “Speakers.”
  5. If you use a headset, make sure it’s picked (not “Default Device”).
  6. Test them:
  7. Speak into your mic—the blue bar should move.
  8. Play the test sound. If you hear nothing, try another device in the list.

Pro tip: Windows sometimes changes your audio device when you plug in something new. Check this every time you switch between laptop speakers and a headset.

b) For Video Issues

  1. Check Webcam Selection:
  2. Same place: Settings > Audio & Video.
  3. See what’s picked under “Camera.”
  4. Preview your video.
  5. If it’s black or frozen, try unplugging and plugging the webcam back in.
  6. Still nothing? Try another USB port or device.

Honest take: Built-in laptop cameras are often terrible. If you have frequent video problems, a cheap USB webcam is usually a big upgrade.


3. Fixing “Can’t Hear” or “Can’t Be Heard” Problems

If someone can’t hear you—or you can’t hear them—don’t jump to blaming Skype just yet.

a) Common Causes

  • Mic or speakers are muted in Skype or Windows.
  • Physical mute button on headset is on.
  • Volume is set to zero.
  • Wrong device selected in Skype or Windows settings.

b) What to Do

  1. Unmute everything.
  2. In Skype, check the mic and speaker icons.
  3. In Windows, click the speaker icon in your system tray.
  4. Check for hardware mute buttons.
  5. Lots of headsets have sneaky mute toggles.
  6. Restart Skype.
  7. Sometimes it just gets confused.
  8. Still broken? Restart your device. It’s not magic, but it flushes out a lot of nonsense.

Ignore: Fancy “audio enhancement” apps or drivers rarely help. In fact, they often make things worse.


4. Network Issues: When the Internet Lets You Down

Audio and video are both bandwidth hogs. If you’re cutting in and out, or your video is blurry/freezing, your network is probably the culprit.

a) Diagnose the Problem

  • Run a speed test. You want at least 1 Mbps up/down for a decent call—more for group video. If you’re barely scraping by, expect trouble.
  • Check your Wi-Fi signal. Weak signal = dropped packets.
  • See if others are hogging the network. Kids streaming 4K video upstairs? That’ll do it.

b) Quick Fixes

  • Move closer to your Wi-Fi router.
  • Kick other devices off the network if you can.
  • Plug in with an Ethernet cable (still the most reliable way).
  • Close any apps using lots of data (Dropbox sync, YouTube, etc.).

Honest take: No amount of Skype tweaking will fix a bad internet connection. Sometimes, you just have to use your phone or find better Wi-Fi.


5. Update Everything—But Don’t Go Overboard

Outdated software causes weird bugs. But constant updating for its own sake can cause headaches, too.

a) What to Update

  • Skype app itself. Get it from the official site or app store.
  • Windows/macOS. Especially audio and video drivers.
  • Webcam/mic drivers. If you use USB devices, check the manufacturer’s site.

b) What to Ignore

  • Don’t download “driver updaters” from random websites. They’re usually more trouble than they’re worth.
  • You don’t need to chase every beta update unless something is truly broken.

6. Skype Settings That Actually Matter

Skype is full of settings, but most of them aren’t worth fiddling with unless you know what you’re doing. Here’s what can help:

a) Audio

  • Automatically adjust microphone settings: Usually safe to leave on, but if Skype keeps making you too quiet/loud, turn it off and set your mic volume by hand.
  • Noise cancellation: Leave on, unless it makes you sound weird or cuts out parts of your voice.

b) Video

  • Choose the right camera. If you have more than one, double-check which one’s active.
  • Adjust video quality. Not really an option in Skype, but if your connection is poor, turning off your camera can help your audio.

7. When All Else Fails: Workarounds and Backup Plans

Sometimes, no amount of troubleshooting will fix a flaky call. Here’s what to try when you’re out of ideas:

  • Switch devices. If your laptop is cursed, try your phone or tablet.
  • Join the call by phone. Skype lets you call in with a number if video isn’t essential.
  • Use a different platform. If Skype refuses to play nice, sometimes Zoom or Teams just works better for your setup.
  • Tell people what’s happening. Don’t just disappear—let your team know you’re having tech issues and trying fixes.

Pro tip: Have a backup plan before your next important call. Test your gear and know how to join from another device if needed.


8. Red Herrings: What Doesn’t Usually Help

Don’t waste time on these:

  • Reinstalling Skype over and over. It rarely fixes device issues.
  • Messing with obscure Windows audio settings. Unless you’ve been changing them, default settings work for most people.
  • Super-fancy mics or webcams. More expensive gear isn’t a cure-all—solid basics and a good network matter more.

9. Quick Reference: Troubleshooting Checklist

Here’s a fast rundown when you’re in a pinch:

  1. Check cables and mute buttons.
  2. Verify correct devices in Skype settings.
  3. Test your internet connection.
  4. Update Skype and your device drivers.
  5. Restart Skype (or your whole device).
  6. Try a backup device or call-in option.

Keep It Simple

Don’t let Skype gremlins ruin your meetings. Most audio and video issues come down to a few simple things: check your gear, double-check your settings, and don’t ignore your internet connection. If it’s still not working, try something else and move on—there’s no prize for suffering through a broken call. Keep it simple, and you’ll spend more time talking to people and less time cursing at your camera.
