#1 Playback issues without timing device

[Chris Hodgetts]

There appears to be an issue with playback of .al
(a-law) and .ul (u-law) files if Asterisk does not have
a valid timing device...

This problem only appeared when the files were played
back out via an external CISCO PSTN interface -
internal calls to asterisk could not replicate the problem.

The .gsm files playback with out any problem in all
situations.

I don't believe, although please contact me if I am
wrong, that it's anything to do with the way the files
are encoded.
