Unable to playback Voicemail

I have spent hours going through older post and bug fixes and cannot seem to get this one resolved. When a VM is left the wav file cannot be played back via extension. The header will play and then it promts to replay or to select 3 for advanced options. I have tried playback via the web page or by SCP the file to another host from /var/spool/asterisk/voicemail/default/xxx/INBOX. I have also verified that the audio.php file is correct. any thoughts or a really big hammer would be appreciated.

Voicemail Module: 2.10.1
ARI 2.10.0rc1.2
OS: CentOS 5.5 Final
FreePbx: 2.10.rc1

yes, I am facing similar problem, I have many voicemails in /home2/spool/astersik but they are not shown in user portal.

could any body please help?
