Please provide any feedback regarding the feasibility of audio output
by bypassing windows mixer and using either Kernel Streaming audio or
ASIO4ALL drivers in WinXP Pro 64 bit. The objective is bitperfect
SPDIF pass-through to to external AV receiver.

I have been reading for 2 weeks everything available on the issue (very
scarce info on x64 XP though), and attempted several OS **clean**
installs, using official and non-official drivers, every time with the
same result: blue screens caused by ksthunk.sys, immediately after
either:

a) using latest Winamp with kernel streaming output plugin, or
b) attempting to run latest Asio4All offline settings panel

However, the system can happily play via SPDIF Dolby Surround DVDs, AC3
xvid/divx, and some ac3 audio files (but not all ac3, neither Dolby or
DTS wavs) using VLC, ffdshow and AC3 filter.

Can XP Pro x64 do kernel streaming, or is it a hardware issue? If you
need more details on the problem, I'd be happy to provide them.

System: Intel E6300 CPU on Asus P5B-VM, onboard Intel HD Audio (Analog
Devices AD1988b)
