Coreaudio backend support needs to be updated

[snailrowen]

I'm using Pyo with sublime on OS.X, and have written the following script

"" from pyo import * import time

def make_sound(a=0, b=0, c=0): voice = SfPlayer(SNDS_PATH + "/transparent.aif", loop=False, mul=1-b) f = Biquad(voice, 101000*a, q=0, type=2) chor = Chorus(f, depth=[1.0,1.6], feedback=c, bal=0.5).out() time.sleep(1) return

s = Server().boot() s.start() make_sound(0,0,0) s.stop() ""

For some reason the script doesn't always finish when I execute it within sublime. When it doesn't, sometimes all the audio on my computer becomes muted until I turn it off and on again. I assume it's some kind of low level hardware problem. Is there any solution?

I'm finding the same problem as above on OSX. It's only an issue on the coreaudio backend; if you change the server below to use 'portaudio' the problem goes away (but you get a warning message about portaudio using deprecated calls to carbon)

from pyo import *
import time

s = Server(audio='coreaudio').boot()
a = Sine().out()
s.start()

time.sleep(3)

The problem hasn't always been there but is certainly present in the 0.8.0 release using 64bit python2.7

The "coreaudio" support in pyo is very old (written under 10.5)... It must be re-implemented on a newer system. It's on my todo list. For the time being, it's safer to use portaudio on OSX.
