Hello! I have a few questions.

Code:
------- sound initialization -------
------ Alsa Sound Initialization -----
dlopen(libasound.so.2)
asoundlib version: 1.0.25
opened Alsa PCM device default for playback
device buffer size: 2047 frames (8188 bytes - 92ms)
period size 511 frames not a power of two. round to next higher
period size set to 511 frames - 2
allocated a mix buffer of 16384 frames (65536 bytes - 743ms)
--------------------------------------
------------------------------------
----- Sound Info -----
sound system is muted
    1 stereo
32768 samples
   16 samplebits
    1 submission_chunk
22050 speed
0x64546fd0 dma buffer
No background file.
----------------------
As you can see in the ALSA buffer_size is 16,384 frames (65536 bytes - 743ms)
How do I reduce it?

Is "22050 speed" means samplerate?
