Re: Can Someone w/ Xonar STX Verify S24_LE?

If OSS appends to each sample eight zero bits which are then ignored by the hardware, why would this have any effect on bitperfectness? What is odd is that through Xonar ST digital coax out, 24-bit files are being truncated to 16-bit e.g. 24/(any samplerate) is being played back and displayed on an...

Can Someone w/ Xonar STX Verify S24_LE?

Does playing a 24-bit file through 'ossplay' (any samplerate) play back through S24_LE: $ ossplay -Rvvvv example-24-bit.wav ... Playing WAVE file 2496.wav, 24 bits Setup device S24_LE ... Or does the file play back through S32_LE: $ ossplay -Rvvvv example-24-bit.wav ... Playing WAVE file 2496.wav, 2...

Re: HDMI and optical output

1. Question The board has an optical output and a coax digital output. But I didn't find an option in ossmix for spdif. I wanted to use oss for that thing, because on my other computer (Xonar DS) I can configure the bit rate to 192 khz for spdif. Is there a chance to configure the ALC-662 for spdif...

Re: Asus Xonar DX

The ST is their top audiophile card (released approximately two years ago). Changes from the STX include a PCI interface, a Cirrus Logic (CS2000) XO clean up chip (and its associated caps) and an interface for a daughter board for 7.1.
