Ticket #31. (You can safely skip the rest of this message :)

IIRC the alsa module gives an error somewhat like this:
"Unable to set hardware parameters: Operation not permitted"

Actually, I didn't find out about this until last thursday.
Last week in IRC somebody had problems using pulseaudio.
Sound was being played too fast. The sound card was similar
to mine, it used the same chip, so I was able to guess that
it was a hardware quirk that I had run into earlier, and
could be fixed in alsamixer. In addition to that it turned
out that the module-alsa-sink wasn't able to use the card,
"Operation not permitted", only device=default (ie. dmix)
worked. That was very strange, after all every other alsa
application was apparently working and my card sure worked
just fine... except that a bit later, for an unrelated
reason, I tried to load the module-alsa-sink myself, and it
turned out that actually I had never done that before. I had
always used the module-jack-sink...

I hope I didn't bore you with this little anecdote :)
