[GnomeMeeting-list] Half Duplex

[Damien Sandras <dsandras seconix com>]

More about half-duplex.
If you do cat /dev/dsp, it opens the soundcard for reading, 
when you do cat /dev/dsp > /dev/dsp it will open the soundcard for reading
and writing. If your soundcard driver is not full-duplex (most of the
kernel drivers), the record will only work when the reading is done.

that is your case... It reads from the device when you are speaking, and when
it is done, /dev/dsp is free to play what you have recorded. that is why there is the 5 seconds delay.
It must work in real time... If it doesn't work in real time, you will
be able to record or to play, but not both at the same time. Installing ALSA
fixes the problem. ALSA drivers will be merged soon in kernel 2.5.

I know that installing ALSA is boring and can be difficult the first
time, but that is the price to pay to be able to use GM, most of the
time...
