[Trans-devel] Re: Audio playback problem in Transcriber with Mac OS 10.4.2

[Jerry G. <j-g...@no...>]

Hi Claude--

This helps but not completely. I can play back the audio following  
your suggestion but there are two further complications:

1. The audio will not advance beyond 10 seconds.

2. No wav which is vital for our efforts to segment the audio.

I will hope for a full fix under Tiger.
