all is fine for 5 minutes, next thing i go to play back a composition again and i either need to press play several times for it to start or when it does there is no sound, only a "pop" in my headphones or a static screech (ouch) please help!
Next I would try switching from the Magix ASIO driver (in the software settings) to WAV or DirectX. Also try the sound card manufacturer's ASIO driver if they are available in the settings window. These can be changed in the playback parameter area and will affect recording as well.
A little experimenting might be needed here to find the best setting which does not introduce noise but has no latency.
I also recommend setting Windows to give priority to background tasks. This will prioritize any audio functions and software using them. You can do this in the Windows System Settings.
Wow... strange behaviour. Do you have plenty or RAM? Does this happen on a specific arrangement/track or does it seem to be random. What type of audio interface do you have? Is it the internal sound card?
