You might have already tried this, but it might work better to use<br>
portaudio to get to ALSA - it can connect with ALSA using callbacks<br>
which the built-in ASA code doesn't. I don't know what difference this<br>
will make but perhaps it will help.<br>
<br>
(try compiling with and without FAKEBLOCKING and THREADSIGNAL defined in<br>
s_audio_pa.c).<br>
