----------------------------------------------

Hi,

Actually I tried with another phone and you are right didn't encounter the issue. Previously was using the built-in mic from the ubuntu system where asterisk is running. 
It means though that asterisk changes some sound parameters when the mic sound is noisy and that these parameters also affect Playback afterward.  They souldn't to my standpoint. In my case it was even affecting pre-recorded, good quality, sounds.
If somebody has the time to investigate would be good.
Anyway this case can be closed. 
Thanks again for your support and fast answer

> Hi,
> When Playback follow Record in a dialplan I get a very noisy output. Obviusly does not come from the file as this one has good sound quality if I play it with "aplay" or if I comment the Record instruction
> extensions.conf :
> [from-internal]
> exten = 100,1,Answer()
> same => n,Record("/tmp/file_in.wav16",1,4)
> ;same => n,agi(halvox2.agi,fr-FR)
> same =>	n,Playback("/tmp/file_out")
> same => n,Hangup()
> Doesn't seem to be related to the file format either as I have tried different file format (sln, sln16, ...). 
>  Any help would be appreciated, thanks in anticipation,
>            Thierry
