<yliu11@hotmail.com></I><BR>>Another bizarry: If I run the
Echo application from the console, I <BR>>can hear a very long delay
(upward to 1,000 ms). I can run the same
<BR>>application from a GrandStream phone (on the same LAN) and hear
<BR>>little delay. What could possibly be
wrong? If it were interrupt <BR>>overload, I'd
hear lots of cracks in my echo, right? I'm not
<BR>>hearing that. Besides, a telephony card is not
involved.</P>
<P>For future reference, I have determined that this was
related to the ISA card used. It may not be entirely due to
card, but when I replaced the card with a newer card (a SIIG Wavetable 5.1 PCI,
identified as CMI8738-MC6 ), things improved significantly.</P>
