hi,
	This might be a a newbie question, but i have openal installed and i am
running into problems.  i have also posted to openal-dev list about my
concerns.

	I have created an ~/.asoundrc file for help with dmix, because i have
had problems playing multiple sound programs at the same time.  This
.asoundrc file helped me use xmms and amarok at the same time.

1. My problem is when i am trying to run an openal program when i am
using one of the other sound programs, the program ran last will block
untill the first program that i started had finished.  This seems
strange to me that some programs will "dmix" and some will not.  Any
ideas on this?


Also, I am thinking about developing and audio app using the openal api,
and i  had some questions that maybe someone could clear up for me.

1.  I am assuming this api wraps around alsa or oss,  i am going to be
using an RME hammerfall dsp and i need to attach some inputs to some
outputs to allow the input from a mic to go to the output which will go
to their headset, (low latency Monitoring).  How is this done, as i have
not found any docs talking about how to send sounds out certain channels?

2.  Some examples i have found do not compile because they are including
the file #include <strstring.h> , which i do not have.  (i am running
gentoo 2005.0, kernel-2.6.11)?

is this a known issue?


thanx in advanced
bj
