I am working on a ALSA card driver that handles a DSP instance. The problem I have is that the triggering mechanism in ALSA to start a PCM has the interrupts disabled, and my dsp framework is actually acknowledging the start trigger with an event after 50 microseconds time that I can't handle because the IRQs are disabled.
Why must you handle the ACK interrupt from inside the trigger?
