Apparently to use "full duplex" with the OSS sound drivers, the program needs to open

two different sound device files, one for reading and one for writing. The OSS

documentation also states that not all OSS drivers support full duplex in this manner, but

some do. I have been unable to find a list of which do and which do not. The OSS

documentation suggests writing a test program. I will let you know if I come across

anything more.

Q. I have installed the openh323 and the pwlib software on the computers however I am

not able to get the mic to record sound and play through the speakers on the other side.

A. If you're running the voice apps (ohphone, simpleh323) under linux, then run aumix to

make sure that the Rec. button is selected for Mic not anything else.

Q. The board is set up such that Ensoniq ES1371 device only plays back. How can I get it

to record?

A. I doubt the hardware or driver are the problem. First, make sure you've got a mic

plugged into the right jack...if in doubt, try them all. You might be able to test the

recording capability with the command line

"cat /dev/dsp > /tmp/test.au".

Stop this with control-C before the file gets too big! To see what you got, just type

"cat /tmp/test.au > /dev/dsp"

You may want to make sure audio playback is working before you do this.

Q. I have to enter my environment variables each time I boot up my computer. I tried to

save it in the bash script .bashrc but they don't get loaded up.

A. The .bashrc script only gets excecuted when BASH is run as a NON-login shell. So if

you were to type "bash" at a bash prompt, a new BASH would start and .bashrc would be

run. ".profile" is probably the file you want, it gets executed when BASH is a login shell.
