The problem is, that the audio and video calculation is in the same
thread - so if there is a heavy calculation in GEM you get an audio
dropout, because there is too few cpu time to also calculate audio ...

You can use 2 instances of pd at the same time: one for audio and one
for GEM (and start this one with -nogui) - then you can send data
between them through netsend/netreceive.
Now the audio and video calculation is seperated and you can say your OS
that the audio-process should have a higher priority.
Alternatively you could also try pdp. There you can use only one
instance of pd and start pdp in a seperate thread.
