Yesterday I made an observation by adding a few printk()s into azx_interrupt() (yes, I know, that's bad). The IRQs come fine when codec parameters are changed in the driver (but of course they are not consumed by snd_pcm_period_elapsed()). They don't come at all (or only one IRQ comes) when they are needed for snd_pcm_period_elapsed(). Could anyone please tell me how to check if they are somehow disabled by mistake?
