I've tried to change period size from 256 to 4096 (2^n values) and
there was no difference.<br>
The only difference was during changing of master sample rate where
I could hear different "position" of interruptions while setting
32kHz or 48 kHz.<br>
Note that buffer size is fixed at 16384 samples (note is from the
driver source code) and I also proved it during experiments.<br>

Just a shot in the dark (it has been a looooong time since I last<br>
played with this stuff):<br>
<br>
Is the period size maybe too large? Does the hardware actually
support<br>
2048 frames? Maybe try 1024 frames. Also maybe try setting the<br>
buffer_size attribute to something that makes sense with the
channel<br>
count and period size. Maybe 2^16 = 65536 Or even bigger? Would
have<br>
to read documentation on the exact semantics. I leave that to you<br>
though ;)<br>
<br>
Good luck,<br>
Flo<br>
<br>
P.S.: There's also a channel #alsa on irc.freenode.org.
Knowledgable<br>
people hang around there, too<br>
