WACUP: The Ultimate Guide for Beginners

WACUP Troubleshooting: Common Problems and Easy Fixes

1. Audio output/no sound

• Check device selection: In WACUP preferences, ensure the correct output device is selected (ASIO/DirectSound/KS).
• Exclusive mode conflicts: Disable exclusive mode in Windows Sound settings or in WACUP if using shared devices.
• Driver issues: Update or reinstall audio drivers (Realtek, ASIO4ALL). For ASIO, try switching to an alternative driver.
• Muted channels/volume: Verify track and master volumes, crossfader, and Windows system volume.
• Test with another player: Confirm hardware works by playing audio in another app.

2. Crackling, pops, or high CPU usage

• Buffer size too low: Increase output buffer/ASIO buffer size in WACUP.
• Background processes: Close heavy apps (DAWs, browsers, virtualization).
• Sample rate mismatch: Match WACUP sample rate to device (e.g., 44100 vs 48000).
• Driver problems: Use manufacturer’s ASIO driver or try WASAPI/DirectSound.
• Plugins/visualizations: Disable DSP, output plugins, or visualizers to isolate the cause.

3. Skipped tracks or playback stuttering

• Disk I/O bottleneck: Move large library files to a faster drive or enable file caching.
• Corrupt file: Try re-ripping or re-downloading the track.
• Database issues: Rebuild the WACUP media library/database.
• Network lag (streaming): Check network connection and increase buffer for network streams.

4. Plugin (DSP) crashes or incompatibility

• Disable third-party plugins: Remove or disable recently added plugins.
• Run in sandbox: Use plugin bridge/sandbox if available to prevent host crashes.
• Check plugin bitness: Ensure 32-bit vs 64-bit plugin matches WACUP architecture or use a bridge.
• Update plugins: Install latest plugin versions and check compatibility notes.

5. UI glitches or theme problems

• Reset UI settings: Restore default layout or switch themes to test.
• Corrupt config files: Close WACUP and delete/rename config files (backup first) to regenerate defaults.
• Graphics driver: Update GPU drivers; disable hardware acceleration if present.

6. Library / metadata problems

• Missing tags: Use a tag editor (within WACUP or external) to update ID3/FLAC tags.
• Duplicate entries: Re-scan library after removing duplicates; clear database cache.
• Incorrect album art: Manually add art or let WACUP fetch from local tags; clear artwork cache if wrong images persist.

7. Problems installing or updating

• Permissions: Run installer as administrator.
• Antivirus blocking: Temporarily disable AV or add installer to exclusions.
• Incomplete install: Fully uninstall, delete leftover config folders, then reinstall the latest build.

8. Streaming service or plugin authentication errors

• Credentials: Re-enter account credentials and check two-factor prompts.
• API changes: Update to the latest WACUP build or plugin; check plugin provider announcements.
• Network/proxy: Ensure no proxy or firewall blocks authentication endpoints.

Quick diagnostic checklist (in order)

1. Restart WACUP and audio device.
2. Test output in another player.
3. Increase audio buffer and match sample rates.
4. Disable DSP/plugins/visualizations.
5. Update audio drivers and WACUP to latest version.
6. Rebuild media library/database.
7. Check logs/error messages and search WACUP support/forums if needed.
