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