Hi,
Paul gave me a code fragment to use the soundcard in fullduplex mode,
(My old code were not able to perform DSP_SET_FRAGMENT, because
of wrong order of soundcard initialization).
But my Turtlebeach on my P133 with Tyan Tomcat motherboard (HX)
locks up the kernel some times.
( I tried 2.2.5 and 2.2.10 )
Is this due to a hw problem of buggy mainboards (from the Audio-quality HOWTO
:-) ) ?
Is there a workaround for OSS/Free ?
Does have ALSA the same problems ?
thanks for infos.
regards,
Benno.
