The ALC883 series 7.1 2 Channel High Definition Audio (HDA) codecs are compliant with Microsoft's UAA (Universal Audio Architecture). The ALC883 series provide 10 DAC channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo output. Flexible mixing, mute, and fine gain control functions provide a complete integrated audio solution for home entertainment PCs.

The ALC883 series support 16/20/24 S/PDIF input and output to offer easy connection of PCs to high quality consumer electronic products such as digital decoders and speakers.

The ALC883 series support host/soft audio from the Intel ICH series chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional audio, and optional Dolby Digital Live and DTS Connect program, the ALC883 series provide an excellent entertainment package and game experience for PC users.
