Hi guys,I'm trying to implement an alsa driver based on the Intel HDA driver.However due to some hardware defects,I'm not able to use interrupt.So I wonder whether there is a way to do the job without the help of interrupt.Can anyone give me a suggestion?
What interrupt are you talking about? ALSA has the ability to discard periodic interrupts but the user-space code needs to explicitly request this mode (eg PulseAudio/AudioHAL). Regular/legacy apps do need an interrupt coming from the hardware. -Pierre
