I don't claim to test these things statistically :-) It's just the
feeling I get after having tested both methods in the same location.

I'd just like to encourage other people to try it out and get their own
feeling for how it works. Perhaps it's better elsewhere, I don't know,
but I would guess that the ALSA state files need some work.

If you don't believe me, just try it yourself. If you get better
results, let the world know!

from the previous mail threads.
