[Openal] two questions

[angelo]

Hi All,

i am working on a simple application, an half.duplex streaming with a 
remote embedded device.
While receiving audio on the pc side, i was wondering if there is a 
fixed total amount limit (samples) of audio to be stored in the AL 
buffers before start to play ?
If i have 4096 bytes (16 bit mono, 2048 samples) the stream is played 
fine, but if i start to play with a received amount of 2048(1024 
samples), i hear a bounce, since the first part is consumed by the 
player and there are not other samples ready for a while.

Also, starting to play, i hear a little glitch, like a "blup". It is 
probably due to the first chunks of samples received that contain some 
noise. Is there a wai to detect if is an AL problem or if the "blup" is 
in the samples received ?

many thanks,
Angelo
