Try to set a system restore point before installing a device driver.
It is highly recommended to always use the most recent driver version available.

True AC-3 playback can be achieved for 6- speaker applications by taking advantage of the STAC9460/61 architecture and combining it with the appropriate decode processor. The STAC9460/61 were designed primarily to support 6-channel audio. The STAC2/63 family also supports a single-line format. For MIC input, the input volume control adjustment range is from 0 dB to 22.5 dB in 1.5 dB steps. The output volume control adjustment range is from 0 dB to -95 dB in. Internal Digital Processing provides a number of advance options, such as independent digital volume controls and mute capabilities as well as a Master Volume control to adjust all DAC simultaneously. Supported ADC sample rates include 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. The STAC9460/62 incorporate stereo 24-Bit variable sample rate ADC's which provide professional quality record capability from the dual microphone inputs or the differential DVD/CDROM inputs.
Supported DAC sample rates include 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz.
The STAC2/63 all support variable sample rate 24-Bit D-A conversion, as well as analog processing. With identical control register organization and communications protocols, the same firmware can be across the family. Packaged in a 28-pin SSOP, the family is completely interchangeable and requires minimal PCB space for implementation.
All four parts communicate via a standard two-wire serial interface providing simplicity in the audio system design. The STAC9461/63 are six and two-channel 192kHz sample rate 24-Bit DACs that use the same Sigma-Delta technology as the STAC9460/62. The STAC9460/62 also include built-in 96kHz sample rate 24-Bit professional quality stereo ADCs along with two differential analog inputs for DVD/CROM and dual MIC inputs for Karaoke applications. The STAC2/63 family all support SigmaTel's AudioUltra™ high-performance mode which delivers 107dB SNR and 3dBV output levels.
The STAC9460/62 incorporate Sigma-Tel's proprietary Sigma-Delta technology to achieve normal mode (1Vrms output) DAC SNR of 104 dB.
The STAC9460/62 are six and two-channel 192kHz sample rate 24-bit, full duplex, audio codecs for use in consumer applications. SigmaTel's family of Consumer Codecs and DACs provide a full array of options for today's high-performance audio equipment.
