ALSA uses quite a few tasklets in the framework and in several drivers. Since we care very much about low latency, many places use tasklet_hi_*.
It would be possible to convert to some GENERIC_SOFTIRQ mechanism, but then we'd want to use a softirq that has higher priority than the 'standard' generic softirq, similar to HI_SOFTIRQ vs. TASKLET_SOFTIRQ.
BTW: Is there a reason why HRTIMER_SOFTIRQ is the lowest-priority softirq instead of being near TIMER_SOFTIRQ?
