There's some evidence that using directsound acceleration (also called hardware mixing) does same thing as using kernel streaming, and enables getting bit-perfect output. However, I haven't been able to verify this, since my Audiophile card doesn't support it.
(ABX anyone ? I'm tired of BS talk about KS sounding "better").
The test was brain-damaged. Mangled sample and non-mangled in my test were both bit identical.How can I force Kmixer to mangle something without making it resample?(which I've ABXed agains non-resampled sample)
