Explore DACs & headphone ampsStart with one complete connection path
For a computer and wired headphones, the basic route is computer to a supported USB DAC/headphone amplifier, then headphones. Select that device in the computer sound settings as well as in the music or meeting app. A cable that charges a device may not carry data. Test one source and one output before adding a hub, monitor or second audio interface.
Headphones, powered speakers and passive speakers
A headphone output, a line output and a speaker output have different jobs. Powered speakers normally need a line-level source; passive speakers need a power amplifier. Check the manual before connecting outputs, and start with volume low. A DAC alone does not turn passive speakers into a complete system.
