By default, AudioRelay captures “Default Output Device.” If you want to stream a specific sound card (e.g., USB headset), select it manually from the dropdown.

AudioRelay often fails on older systems because its built-in virtual audio drivers won't install. You can bypass this by using a third-party virtual cable: Download VB-CABLE

If you’re running a legacy laptop, an old desktop tower, or a netbook with Windows 7 32-bit, AudioRelay can breathe new life into it, enabling seamless audio streaming without buying new hardware.
