[alsa-devel] HR timer 1000Hz limit since kernel 4.4.0-77

Hello, ever since kernel 4.4.0-77, there seems to be
  a limit on the ALSA HR timer, I can't set it above 1000Hz
  (snd_timer_params() fails with -22 invalid argument).
I used to be able to set the rate much higher than that.
Been observed in two completely different distros, one with
  a much newer kernel. How can I overcome this limit?
Thanks.
