Frequently Asked Questions (FAQ)
Do I need to install an app on my phone or laptop?
No. This tool runs entirely within your web browsers. You do not need to install any software, virtual audio cables, or mobile applications.
Why am I getting no sound?
The most common issue is forgetting to check the "Share tab audio" checkbox when the browser asks you which tab to share on the laptop. Additionally, some mobile browsers block autoplaying audio. If you don't hear anything, tap the "Tap to Unmute/Play Audio" button that appears on the phone screen.
Why does Netflix or Amazon Prime show a black screen / no audio?
Browsers use DRM (Digital Rights Management) to prevent piracy on premium streaming sites like Netflix, Disney+, and Hulu. When a browser detects that you are capturing the tab, it automatically blackouts the video and mutes the audio track. This tool works best for standard web video (YouTube, Vimeo, Reddit) or local video files dragged into your browser.
How do I fix audio lag/latency?
If the audio is slightly behind the video, it is due to your Wi-Fi router. To fix this, connect your phone to the laptop with a USB cable, go to your phone's connection settings, and turn on USB Tethering. Refresh this page and connect again. The audio will travel over the wire instantly.
