   Hehe, agreed.
   But this is not supposed to be a wish-list, but rather a list of things
   that people keep asking about.

   As I don't have a 64bit SMP machine I just mentioned it as it
   used to be a problem for a long time and I haven't noticed that
   it had been resolved. But if it is working now reliably that's great!

   for me too and probably most others, but Joel's regular mails are proof
   that there are at least some machine/kernel combinations that don't
   work reliably

   It doesn't seem to have anything to do with the snd_ad1889 driver,
   but with ALSA itself. I've never been able to get proper sound using
   native ALSA interface (using ad1889 and also usb-audio)
