This allows capture notifications to make progress when ordinary workqueue workers are delayed by CPU contention. Playback and ordinary capture keep schedule_work(). This preserves the existing priority proposal without mixing RESET or lifecycle changes into it. It provides no hard real-time deadline and cannot prevent a userspace reader from overrunning its buffer.
