When playing a PC game that supports virtual surround, we recommend setting the USB output to match the game's channel configuration (5.1ch or 7.1ch). If the settings do not match, sounds from unused channels may be routed to unintended channels, which can result in audio issues.
For detailed instructions on configuring output settings in Windows 10/11, please refer to the section "Outputting 5.1 / 7.1 audio from a Windows PC" in the BRIDGE CAST ONE Owner's Manual.
