Just a shot in the dark (it has been a looooong time since I last
played with this stuff):

Is the period size maybe too large? Does the hardware actually support
2048 frames? Maybe try 1024 frames. Also maybe try setting the
buffer_size attribute to something that makes sense with the channel
count and period size. Maybe 2^16 = 65536 Or even bigger? Would have
to read documentation on the exact semantics. I leave that to you
though ;)

Good luck,
Flo

P.S.: There's also a channel #alsa on irc.freenode.org. Knowledgable
people hang around there, too
