in

Quick checklist (start here)

  • Restart Evaer and the target app (Skype/Teams).
  • Ensure Evaer is running with required permissions (microphone, camera).
  • Confirm you have the latest Evaer version and latest Skype/Teams build.
  • Check disk space and destination folder permissions.
  • Verify audio/video devices are selected and working.

If those basics don’t resolve the issue, read the detailed sections below.

1. Installation and version issues

Symptoms: Evaer won’t open, crashes on start, or features are missing.

Likely causes:

  • Outdated Evaer or Skype/Teams version mismatch.
  • Corrupted installation files.
  • Conflicts with other recording or virtualization software.

Fixes:

  1. Update both Evaer and the target app to the latest stable releases.
  2. Reboot your computer after updating.
  3. If the problem persists, uninstall Evaer completely, reboot, then reinstall from the official Evaer site.
  4. Temporarily disable other call-recording tools, virtual audio drivers (e.g., Voicemeeter), or screen-capture utilities that may conflict and test again.
  5. Run Evaer as administrator on Windows (right-click → Run as administrator) to rule out permission issues.

2. No audio captured (local, remote, or both)

Symptoms: Video is recorded but audio is missing for one or both participants, or only one side of the conversation is present.

Likely causes:

  • Incorrect audio device selected in Evaer or Skype/Teams.
  • System privacy settings blocking microphone access.
  • Exclusive mode or sample-rate conflicts.
  • Remote audio routed through a different device or Bluetooth with poor support.
  • Firewall/antivirus interference for virtual drivers.

Fixes:

  1. Check Evaer audio settings: ensure the correct recording device (system default or specific microphone/speaker) is selected.
  2. In Skype/Teams audio settings, verify the same working microphone and speakers are chosen; test them within the app.
  3. In Windows Sound settings:
    • Open Sound Control Panel → Recording/Playback devices → Properties → Advanced.
    • Disable “Allow applications to take exclusive control of this device” for problematic devices.
    • Ensure sample rates match (e.g., 44.1 kHz or 48 kHz) between OS, Evaer, and Skype/Teams.
  4. Check privacy settings (Windows):
    • Settings → Privacy & security → Microphone → Ensure apps are allowed to use the microphone.
  5. For missing remote audio: ensure system audio is not muted and that Evaer is permitted to record system sound.
  6. If using Bluetooth headsets, test with wired headphones—some Bluetooth stacks don’t expose stereo system audio properly.
  7. Temporarily disable firewall/antivirus or add exceptions for Evaer and Skype/Teams to see if that restores audio.

3. Video recorded but black screen, or blank/empty file

Symptoms: Output shows black video, only audio, or file fails to save.

Likely causes:

  • Wrong video source selected (virtual camera, GPU acceleration conflict).
  • Hardware acceleration or GPU driver incompatibility.
  • Privacy settings blocking camera access.
  • Insufficient disk space or file permission issues.

Fixes:

  1. Confirm camera selection:
    • In Evaer’s settings and Skype/Teams, ensure the correct camera is selected.
    • If using a virtual camera (OBS VirtualCam, ManyCam), try switching to the physical camera to isolate the issue.
  2. Update graphics drivers and camera drivers to latest versions from manufacturer websites.
  3. Disable hardware acceleration in Skype/Teams (or in system settings) temporarily to test for GPU conflicts.
  4. Check camera privacy:
    • Windows: Settings → Privacy & security → Camera → Allow apps to access camera.
  5. Verify destination folder exists, has write permissions, and has free disk space. Try saving to a different folder or drive.
  6. If files are corrupted after recording, try lowering resolution/frame rate in Evaer settings and record a short test file.

4. Out-of-sync audio and video

Symptoms: Audio lags behind video (or vice versa), sync drift over long recordings.

Likely causes:

  • System resource overload (CPU, disk I/O).
  • Incorrect frame rate or sample rate settings.
  • Encoding settings too aggressive for hardware.
  • Background processes causing interruptions.

Fixes:

  1. Lower recording resolution and frame rate in Evaer (e.g., 720p or 15–20 fps) to reduce CPU/GPU load.
  2. Match audio sample rate (Windows Sound → Properties → Advanced) to Evaer’s audio settings to avoid resampling drift.
  3. Close unnecessary background apps, especially other audio/video tools, browsers with many tabs, or heavy rendering tasks.
  4. Use a faster disk (SSD) for recording destination, or ensure disk isn’t near full.
  5. If CPU spikes are intermittent, check Task Manager to find the culprit and consider disabling it or changing its priority.
  6. If the problem only appears with long recordings, try splitting recordings into smaller segments when possible.

5. Poor audio or video quality (noise, choppy, low-res)

Symptoms: Recording sounds tinny or noisy; video stutters or is pixelated.

Likely causes:

  • Low bandwidth/poor network for remote participant streams.
  • Microphone quality or incorrect encoding bitrate.
  • Insufficient CPU resources for chosen bitrate/resolution.
  • Background noise or echo from participant setups.

Fixes:

  1. For remote call quality issues, ask participants to switch to wired Ethernet or improve Wi‑Fi signal; limit other network-heavy activities.
  2. Increase audio/video bitrate in Evaer only if CPU and disk can handle it; otherwise lower resolution to maintain smooth playback.
  3. Use a better microphone or use headset mics instead of laptop mics to reduce room noise and echo.
  4. Enable noise suppression or echo cancellation features in Skype/Teams where available.
  5. Record a short test clip while adjusting bitrates and observe the trade-off between quality and performance.

6. Recordings not saved or fail to open

Symptoms: Recording completes but file is missing, zero-byte, or won’t play.

Likely causes:

  • Destination directory issues (permissions, full disk).
  • Antivirus deleting or quarantining files.
  • File naming conflicts or illegal characters.
  • Crashes during saving due to insufficient resources.

Fixes:

  1. Check the destination folder immediately after recording; search for recently modified files.
  2. Check antivirus/quarantine logs and add Evaer and the recording folder to exclusions.
  3. Ensure file paths do not include special characters or overly long paths (Windows MAX_PATH limits).
  4. Try saving to a different drive or folder (e.g., Documents or desktop) and test.
  5. If files are zero-byte, monitor resource usage during recording and consider lowering recording quality or using a faster disk.

7. Licensing and activation problems

Symptoms: Evaer shows trial limitations, prompts for license repeatedly, or features disabled.

Likely causes:

  • License key not entered correctly.
  • Expired trial or license mismatch.
  • Firewall or proxy blocking license verification.

Fixes:

  1. Re-enter the license key exactly as provided. Copy-paste to avoid typing errors.
  2. If license server verification fails, temporarily disable firewall/proxy and try activation—then re-enable and create an exception if needed.
  3. Contact Evaer support with purchase details if the license still won’t validate.

8. Integration quirks with Skype vs. Microsoft Teams

Notes:

  • Skype historically exposes system audio differently than Teams; some Evaer features may behave differently across apps.
  • Teams may get frequent updates that change how third-party recorders hook into its audio stack.

Tips:

  1. Keep both the recorder and target app updated.
  2. If a new Teams/Skype update introduces a regression, check Evaer’s support/announcements for compatibility notes.
  3. For critical recordings, perform a quick test recording before the real call.

9. Advanced diagnostics

Steps to collect helpful info before contacting support:

  1. Reproduce the issue and note exact steps, timestamps, and settings used (resolution, bitrate, audio source).
  2. Save log files if Evaer provides them (look in Evaer installation folder or help menu).
  3. Capture system details: OS version, Skype/Teams version, Evaer version, CPU/GPU, amount of RAM, disk free space.
  4. If possible, record a short sample that demonstrates the issue and attach it when contacting support.
  • Resolution: 1280×720 (720p) for most meetings.
  • Frame rate: 15–24 fps for talks and interviews.
  • Audio sample rate: 48 kHz (match Windows/Skype/Teams).
  • Destination: SSD with free space > 10× expected file size.
  • Run as administrator if you encounter permission issues.

When to contact Evaer support

  • Reproducible crashes, corrupted files, or license activation failures after you’ve tried the fixes above.
  • Compatibility regressions after a recent Skype/Teams update.
  • Provide detailed steps to reproduce, sample files, and the system/log information from the diagnostics section.

Troubleshooting recording tools is often about isolating variables: device selection, permissions, system resources, and app compatibility. Follow the ordered steps above, run short tests after each change, and you’ll usually identify the culprit quickly.
