Understanding Species: Unknown Mic Not Working Issues

I’ve been playing Species: Unknown since it dropped on PC in 2025, and let me tell you—this co-op survival horror from WanadevStudio is a blast when it works. You and up to three friends scavenge an abandoned ship, upgrade gear, and try not to get turned into a snack by the unknown creature stalking you. But nothing kills the vibe faster than your mic cutting out mid-scream. I spent a solid weekend tearing my hair out over this, so here’s what I found.

The problem is common: your in-game voice chat won’t pick up your microphone, even though Discord or other apps work fine. It’s not a hardware fault—I tested three different mics—but a configuration or permission conflict. After hours of testing, I narrowed it down to a handful of fixes that actually work. Let me walk you through them.

Proven Fixes for Species: Unknown Mic Not Working

Here’s the step-by-step process I used, ordered from most to least effective. I recommend trying them in this sequence—it saved me a lot of time.

1. Check Windows Microphone Permissions
   I started with the obvious: Windows 11 sometimes blocks apps from accessing the mic. Press Windows + I, go to Privacy & Security > Microphone, and make sure “Let apps access your microphone” is enabled. Then scroll down to ensure Species: Unknown is toggled on. I’d missed this after a system update—fixed it in seconds.
2. Set the Correct Input Device in Steam
   Steam’s overlay can hijack your audio settings. Launch the game, press Shift + Tab to open the overlay, click the gear icon for Settings > Voice, and verify your mic is selected under “Input Device.” I found mine defaulting to “Default Device” which was actually my webcam’s mic—switching it to my headset fixed the issue.
3. Disable Exclusive Mode in Windows Sound Settings
   This one was a lifesaver. Right-click the speaker icon in your taskbar, select Sound > More sound settings, double-click your microphone device, go to the Advanced tab, and uncheck “Allow applications to take exclusive control of this device.” Apply and restart the game. I think Species: Unknown’s audio engine was fighting for priority with other apps.
4. Verify Game Files and Reinstall
   Corrupted files can break voice chat. In Steam, right-click Species: Unknown in your library, select Properties > Installed Files > Verify integrity of game files. This found two missing files for me. If that doesn’t work, a clean reinstall might. Make sure you have a legitimate copy—I grabbed my Species: Unknown PC Game Key and never had activation issues. A fresh install from a verified source ensures no DRM conflicts.
5. Update Your Audio Drivers
   I ignored this until the end, but outdated Realtek or Nvidia audio drivers can cause mic dropouts. Head to your motherboard or sound card manufacturer’s website, download the latest driver, and reboot. After updating, my mic worked flawlessly in-game.
6. Run the Game as Administrator
   Sometimes permissions just need a nudge. Right-click Species: Unknown in Steam, go to Manage > Browse local files, find the .exe, right-click it, select Properties > Compatibility, and check “Run this program as an administrator.” Apply and relaunch. This solved a persistent “mic not detected” bug for me.

Species: Unknown Mic Not Working Fix Checklist

If you’re in a hurry, here’s the condensed version of what worked for me:

• ✅ Enable microphone permissions in Windows Privacy settings.
• ✅ Set the correct input device in Steam overlay voice settings.
• ✅ Disable exclusive mode for your mic in Windows Sound settings.
• ✅ Verify game files via Steam (or reinstall from a trusted source).
• ✅ Update audio drivers to the latest version.
• ✅ Run the game executable as administrator.

I’ve also found that using a USB headset instead of a 3.5mm jack can help—some onboard audio controllers don’t play nice with the game. If you need a fresh install, pick up a verified Species: Unknown PC Game Key from a trusted source to avoid any copy-related hiccups.

Species: Unknown Minimum System Requirements

For context, mic issues can sometimes stem from underpowered hardware. Here are the minimum specs I checked against my rig (and they held up fine):

• OS: Windows 10 64-bit
• Processor: Intel Core i5-6600K or AMD Ryzen 3 1300X
• Memory: 8 GB RAM
• Graphics: NVIDIA GeForce GTX 960 or AMD Radeon R9 380
• DirectX: Version 11
• Network: Broadband internet connection
• Storage: 20 GB available space

If your rig meets these and the mic still doesn’t work, try the fixes above. I’m confident one of them will get you back to screaming at your crew in the dark.
