Hi,
If I open multiple instances of Pd in Ubuntu (doesn't matter whether vanilla or extended or mixed), only the first one has sound. No matter whether I set "alsa" or "oss" in Media.
(btw I'm sure I had seen also "portaudio" listed but now it's gone)
Usually there's no problem in having multiple applications send sound to the same output device (not sure whether the same can be said about input)... Is there something I'm missing that will allow multiple Pd's to send sound to the output just as multiple applications do?
thanks m.
I strongly advise using "Jack" as the audio engine in Ubuntu. It allows you to have zillions of apps connected.
If you don't know how to configure/install jack we can help. I have used OSS/ALSA a lot but jack simplifiies a lot of the troubles and allows more connectivity between audio executables (pd, ardour, effect suits, in/outs, etc..).
install jackd (the audio server) install qjackctl (graphical front-end)

Ohhh! Thanks. I thought Jack was ("only") a sort of "virtual audio cable" for connecting the output of an app to the input of another. I guess it is _also_ that.
Anyway, just out of curiosity, why cannot two pd's using oss or alsa both work simultaneously while other apps apparently can?
Thanks m.
Because Pd needs exclusive access the audio card. Jack abstract that creating various streams of audio data and then routing it to the playback device.

because OSS and ALSA are designed for exclusive usage of your soundcard devices (though with the latter you can set it up in a way that allows you more complicated stuff). other apps appearantly use consumer grade frameworks like pulseaudio and the like to allow multiple apps play to a single device. however, it's most likely neither OSS nor ALSA they are using.
