Hi everyone, We have an usb audio device that expose 8 channel capability in 16bit at 48k sample rate. We use MS generic usbaudio.sys driver. Will 8 channels wave_format_extensible files play in full 7.1 across all OSes? I can't seem to get confirmation of this anywhere, and my early tests show that Win2k mixes the front left, front right and center channels together to form channel 7&8... thanks for any info, Martin _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
