Or, just copy alsa-kernel/drivers/dummy.c to your tree. There is no other changes except for documentation.
I will now try to compile from it's own snapshot tree, doing the ./configure.
I'm sorry to say that actually it was worst than before for me, so maybe centos kernel is "non collaborative" (eg: no high res timers).
Then it falls back to the system timer, so it must work still. To be sure, set hrtimer = 0 instead 1 in dummy.c.
If this still doesn't work, I'd recommend you to add a debug printk at each call of dummy_systimer_pointer(). Print the returned result together with jiffies value.
