asterisk users - Dec 2007 - Soundcard necessary on an asterisk server to get output of playback()??

Hi,

I' still fighting the problem, that I can talk from one SIP phone to 
another, but I can't hear the output of the playback or similar 
applications:

         exten => 202,1,ANSWER()
         exten => 202,2,PLAYBACK(tt-monkeys)
         exten => 202,3,HANGUP()

When I dial 202, asterisk show the following on the cli:

-- Executing [202 at local:1] Answer("SIP/user1-0827ebe8",
"") in new stack
-- Executing [202 at local:2] Playback("SIP/user1-0827ebe8",
"tt-monkeys")
in new stack
-- <SIP/user1-0827ebe8> Playing 'tt-monkeys' (language
'de')

Yes, the file tt-monkeys exist in /var/lib/asterisk/sounds and the 
subdirectory de.

No, there is no error message even if turn on debugging. :-(

Besides this strange behaviour, I was wondering whether the asterisk 
server needs an soundcard to send the output of e.g. the playback 
application to the phone.

BTW, this is asterisk 1.4.13

I would be really happy, if someone has an idea how to solve this problem.

Thanks in advance,

Stefan

My quick guess would be that it's a timing issue.  You didn't mention
whether you are using a Zaptel device or ztdummy.

I know this sounds like I'm being a smart***, but I'm not...  try
this...
rub the mouthpiece of the file while the sound file is playing and see if
you hear any of the file.  If so, I would definitely say you have a timing
issue.

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

Hi,

I have found a solution for my problem or at least I can hear the output
of PLAYBACK() and the voicemail system.

Since some of you suggested a timing problem, I removed the ztdummy and
zaptel modules, but this had no effect.

For whatever reason I have to insert a WAIT(1) in front of every
application that returns an output. Well, now the context looks like
this and it works:


        exten => 202,1,ANSWER()
        exten => 202,2,WAIT(1)
        exten => 202,3,PLAYBACK(tt-monkeys)
        exten => 202,4,HANGUP()

Does anyone have an explanation why I need the WAIT() ?

Thanks for your help last night.

Stefan

BTW: As far as I can see, no one answered the question that I entered in
the subject line: Do I need a sound card in the server, does it have any
effect?
