[asterisk-users] Soundcard necessary on an asterisk server to get output of playback()??

[Matthew Yingling]

Search for "ztdummy, zttest" and "Zaptel Issue 11153" in the Dev Mailing
List.  You might have a buggy kernel.

Hi,

I'm using ztdummy, and yes, I guess your're right - it seems to be a 
timing problem, because I found the following messages in /var/log/messages:

Dec  3 22:51:36 asterisk kernel: [25713.830465] printk: 249 messages 
suppressed.
Dec  3 22:51:36 asterisk kernel: [25713.830468] rtc: lost some 
interrupts at 1024Hz.

BTW:
 >name -a
Linux asterisk 2.6.22-14-386 #1 Sun Oct 14 22:36:54 GMT 2007 i686 GNU/Linux

But what does "lost some interrupts at 1024Hz" tell me? And if it is 
related to my problem, how do I solve it?

Thanks for your help,

Stefan
