Intel® High Definition Audio (Intel® HD Audio) Controller Capabilities

The Intel® HD Audio controller is the standard audio host controller widely adopted in the PC platform, with industrial standard Intel® HD Audio driver software available for Microsoft* Windows* and many other Linux* based Operating Systems. Intel® HD Audio controller capabilities are listed as follows:

  • Baseline Intel® HD Audio operation with legacy DMA transporting audio stream to / from audio codecs, with host processor carrying out the audio processing
  • Low power audio operation with offload DMA transporting audio stream to / from the Audio DSP offload engine offloading the audio processing from host processor
  • Ability transport audio stream to various audio codecs speaking different link protocols with the same audio host controller view from SW stacks
  • PCI / PCI Express* controller
  • Supports data transfers, descriptor fetches, and DMA position writes using VC0
  • Independent Bus Master logic for 16 general purpose DMA streams: 7 input and 9 output
  • Supports variable length stream slots
  • Each audio stream supports up to:
    • 30 streams (15 input, 15 output)
    • 7 input DMA streams and 9 output DMA streams
    • 16 channels per stream
    • 32 bits/sample
    • 192 kHz sample rate
  • Supports memory-based command/response transport
  • Supports optional Immediate Command/Response mechanism
  • Supports output and input stream synchronization
  • Supports global time synchronization
  • Supports MSI interrupt delivery
  • Support for ACPI D3 and D0 Device States
  • Supports Function Level Reset (FLR)
  • Support Converged Platform Power Management (CPPM)
    • Support 1 ms of buffering with all DMA running with maximum bandwidth.
    • Support 10 ms of buffering with 1 output DMA and 1 input DMA running at 2 channels, 96 kHz, 16 bit audio.
