Output interfaces

Two-channel and multichannel outputs can be routed to a variety of interfaces, including:

  • HDMI
  • S/PDIF
  • Line level
  • Speakers
  • Headphones

Certain tests must be repeated on all digital output interfaces (such as HDMI and S/PDIF) supported by the product under test. The Dolby Digital Plus 7.1-channel audio decoding and channel mapping test case specifically requires testing on the digital interfaces.
