    Fair enough - I don't see any technical
    reasons why alsa *couldn't* perform as
    well, latency wise, as oss.

    Some folks on this list had been doing latency
    profiling on their kernels during the past year
    (sorry, I don't remember the exact dates) and
    surprisingly the alsa driver was showing up
    as one of the top sources of latency - IIRC one
    possible explanation was "in-kernel mixing".

    Thanks for the feedback, I'll have to do some
    testing of my own and see what the situation
    is at this point - I'd be very happy to learn that
    my concerns are outdated and already resolved.
