Required hardware forSpeakup

I'm old enough to remember a day when this didn't work on Windows
either. Admittedly, that was some time ago.

Remember that the audio environment in LInux is still not fully settled.
The kernel moved from oss to alsa beginning with 2.6.x kernels.
Meanwhile, alsa continues to evolve so much so that it can feel like
quicksand with device name changes, .asoundrc syntax changes, and new
technologies like dmix arriving as recently as the current alsa version,
1.0.9.

On top of that there's esound, and there's arts, and there's mas, and
there's jack for the high-end, professional audio crowd.

If I were to hazzard an opinion, I would conjecture that sound support
is regarded as a consumer feature, and Linux has not necessarily been
consumer oriented. Of course for us it's much more than a nice to have
consumer feature, but that's another story.
