If you're experiencing audio/video synchronization problems while using external audio or video equipment, it may be due to hardware latency.

While some devices come with come with advanced latency configuration options, many consumer-grade devices do not. Make note of problem combinations, and contact your device's manufacturer for assistance with possible remediation options.
