Hi,

it is possible to play (e.g. an au-file with audioplay) and record an input of 
this soundcard at the same time?

How or with which programs can I use the full duplex feature?

When I'm starting audioplay (after I set my working ich-soundcard with 
audioctl to full_duplex) and after this audiorecord, so audiorecord returns 
with an error because /dev/sound0 is already used (by audioplay).

Thank you very much,

Falk
