for days trying to resolve this, and any help someone can give me would be very
much appreciated.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have an Asterisk box that is basically a P4-3GHz, a
Digium-recommended SuperMicro X5SSE-GM motherboard, 2GB RAM, 250GB IDE
hard-drive with UDMA, a SoundBlaster Live! 24 sound card, a Digium Wildcard
TE110P, and a Digium Wildcard TDM400P with 4 FXS modules. Right now the
Ethernet is hooked up directly to a single VoIP phone (Grandstream
GXP-2000). I’m running kernel 2.6.12.3.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>THE PROBLEM: The problem I am having is when using the
speakers hooked into the SB Live! 24 card. When I call through like an
intercom (my intention) and have the dialplan play an announcement (for testing
purposes, I have used both the included “you-sound-cute” and
“lots-o-monkeys”), it’s very choppy – to the point of
being laughably unacceptable. Then when I talk over the
“intercom,” my voice sounds just as choppy. Interestingly
enough, when I go to the console and dial the demo included in the Asterisk
sample configuration files (which I left in for testing), the woman’s
voice sounds fine (for 8KHz anyway). But the demo is an IVR menu, and
when I dial “2” for more information (for example), it starts
playing the next message – all choppy.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have read hundreds of mailing list posts and dozens of
how-tos and diagnostics suggestions online. I’ve tweaked out
motherboard settings, kernel options, hard drive parameters, etc. with no
success. I’ve tried literally dozens of ALSA configurations
thinking that the problem could be there. I’ve focused on kernel
and IRQ optimizing, ALSA configuration, Asterisk configuration, and Zaptel
configuration (in case it’s a timing problem) with no success. I
have been completely unable to resolve this problem. I have a PRI line on
its way, but since “zttest” suggests the internal timing of the
TE110P is accurate within Digium specs, I don’t think external
synchronization will help anything.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Maybe the SB Live! 24 isn’t the best card to use for
the console intercom on this system. But supposedly ALSA has full support
for it.<o:p></o:p></span></font></p>
