Rosewill RCAD-11002 USB to HDMI Adapter chipset details
 

Which chipset used Rosewill RCAD-11002 USB to HDMI Adapter ?? (driver displaylink)

Hello,
Difficult to know.
DisplayLink sells chips, we don't make products.
From the product specifications, I would say it's a DisplayLink DL-1x5 series.
This means the product doesn't necessarily handle audio.
Kind regards,
Alban
