7.1 Channel High Definition Audio Codec 1 Track ID: JATR-1076-21 Rev. 1.3 1. General Description The ALC861 7.1 Channel High Definition Audio codec with UAA (Universal Audio Architecture), features four stereo DACs and one stereo ADC. The ALC861 is designed for multimedia PC systems. The ALC861 provides 7.1 output channels, along with mixing, mute, and gain control functions to provide an integrated audio solution for PCs. Parts of analog IO are input and output capable, and three headphone amplifiers are also integrated to drive earphones on front and rear panels. The ALC861 supports S/PDIF output function and a sampling rate of up to 96kHz, offering easy connection of PCs to high-quality consumer electronic products such as AC-3 decoders/speakers, and mini disk devices. The ALC861 supports host/soft audio from the Intel ICH chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and software utilities like Karaoke mode, environment emulation, software equalizer, and HRTF 3D positional audio, the ALC861 provides an excellent entertainment package and game experience for PC users.

Reset and Initialization There are two types of reset within an HDA link:
- Link Reset. Generated by assertion of the RESET# signal. All codecs return to their power-on state
- Codec Reset. Generated by software directing a command to reset a specific codec back to its default state An initialization sequence is requested after any of the following three events: 1. Link Reset 2. Codec Reset 3. Codec changes its power state, e.g., hot docking a codec to an HDA system 7.3.1. Link Reset A link reset may be caused by any of the following three events: 1. The HDA controller asserts RESET# for any reason (power up, or PCI reset) 2. Software initiates a link reset via the ‘CRST’ bit in the Global Control Register (GCR) of the HDA controller 3. Software initiates power management sequences. Figure 12, page 16, shows the ‘Link Reset’ timing including the ‘Enter’ sequence (n~r) and ‘Exit’ sequence (s~v)
