Can't get the Server to shut down full (I think) when using ASIO4ALL

[Jon]

Hi there,

Sorry to be blitzing the list today! I've got a further issue, now on windows (win7, 32 bit). When using the ASIO4ALL driver as a backend from pyo the Server fails to shutdown (or the script never quits, which I assume is because the server hasn't shut down). Sounds play fine. I've tried with several time.sleep() calls because I know there has been an issue in the past where the server fails to shutdown if its stop() call hasnt yet completed.

Is this a known issue? Should I just avoid use of ASIO for now?

cheers,

Jon

This is the script I'm running:

#--------------------------------------------

import pyo, time

devNames, devIDs =pyo.pa_get_output_devices()

for n, devName in enumerate(devNames):

    if 'ASIO' in devName: #set this to 'Primary' to use DirectSound backend (fine)

        devID=devIDs[n]

s = pyo.Server(duplex=0)

s.setVerbosity(4)

s.setOutputDevice(devID)

s.boot()

time.sleep(0.5)

s.start()

print 'server started'

s.stop()

time.sleep(0.5)

s.shutdown()

time.sleep(0.5)

print 'server stopped'

#--------------------------------------------

and this is the output:

#--------------------------------------------

pyo version 0.6.2 (uses single precision)

PortMidi warning: Something wrong with midi device!

Portmidi closed

server started

server stopped

#--------------------------------------------

Hi,

ASIO is the only way to achieve low latency with pyo on Windows. I never got problem with the ASIO driver but can you see if the last change (previous mail) makes things work better?
