    I'm not certain that this is a VAIO- or libretto-specific thing. I have a
    cheap ESS1869 card on a normal PC and when I request a rate of 44100Hz, OSS
    reports back that I'm actually running at 44198Hz or something like that.
    My code says fine and uses that as its samplerate (it does realtime
    resampling) but it plays considerably slower. In fact, it sounds about one
    or two semitones under what it should be (more than the 44198/44100
    difference - one semitone would be 46722Hz). I will investigate further,
    but I suspect there's a samplerate problem in the ESS driver in general.

    Incidentally, ALSA ( drivers work fine.
