Oggetto: [Asterisk-Users] Sound Quality Problems
Thanks for reading this. I've been pulling hair for days trying to resolve
this, and any help someone can give me would be very much appreciated.
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.
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.
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.
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.
Any help at all is greatly appreciated.
Thank you.
