[Pksampler-devel] Re: Porting pkaudio to ppc

[Patrick S. <pat...@gc...>]

I did realize that test_unittest.py hasn't really been updated or re-thought 
since I made jack the default audio driver. The problem is that 
jack_client_connect() doesn't start the server very well (at least on my 
machines), and if you don't start the server your self (`jackd -d alsa -r 
44100`), the audio tests won't work. Most of the tests in the above file 
focus on network communication using the pkaudio protocol, though.
