Abstract
An operating system is logically separated into a partition for a kernel and a partition for an audio subsystem having logically separate subpartitions. An audio application generates a first audio datastream by executing the audio subsystem. The context of a process for processing the first audio datastream is preserved in a first subpartition. The processing of the first audio datastream with the process takes place in a second subpartition. When the process commits an access violation, the process is recovered by restoring in the audio subsystem the preserved context from the first subpartition.
