asterisk users - May 2003 - Sound Quality - Part 2 (mp3)

Hi All,

Thanks to the people that responded to my question. The suggestion of using
SJphone instead of the Xten phone resolved the problem :-)

I now have another sound related problem! I've installed mpg123 and ensured
that the binary is copied to /usr/bin as well as the default install location.
mpg123 plays mp3s back perfectly via the desktop speakers, but when I playback
an mp3 via the Queue function the sound is very distorted. I've tried
re-encoding the mp3 file but this has no obvious effect.

Voice conversations (ISDN <-> SIP client) sound fine, as does the initial
"welcome" message that is stored in gsm format. It is only the MP3
playback that suffers. Asterisk does seem to be having problems with mpg123.
When I try to "restart gracefully" I get an "ouch.... broken data
pipe" (or similar) message and have to kill the mpg123 process. Looking
through the archive I've seen mention of the "ouch" error, but no
resolution was offered.

Does anyone have any hints or tips?

For the record I'm running asterisk under RedHat 9 using a XP1600+
processor, Elsa PCI ISDN card and 384MB Ram.

Thanks,
Nathan.

I was getting this too, it's probably caused because there is no code in
asterisk to shutdown mpg123 when you restart or shutdown asterisk.  I
havn't gotten around to it, but a simple shell script that does a ps and
greps for mpg123 and pipes it word count would do the job. If u have moh
configured propperly you should only ever have 2 running proccesses of
mpg123 if the wc is > 2 then you could kill the pids.  I wouldn't be too
hard to do at all and I'm sure Mark could add very easily to the
shutdown and restart scripts.
