[Pythonmac-SIG] Audio_mac.py fails in writeframes

[punch]

I'm running 'OS X' 10.4.10 and python 2.5.1 on a MacBook Pro SR. When I 
try to run any of the audio demos, specifically Audio_mac.py, I get 
errors. The error is in the writeframes method. It appears to try and 
pack the constant extSH (set to 0xFF) as a signed byte, which it cannot do.

I've searched all around and found one guy on the net with this problem 
but no answer. I can over-ride the writeframes method but what should 
extSH be?

Any help appreciated.

Change the struct.pack format from 'llHhllbbl' to 'llHhllBBl'.

The code predates the distinction between signed and unsigned bytes  
in struct.pack.


But be warned that this also shows how well-maintained the code is:-)
