New subject: jack feature request

...
   the thing to do is to
  fire up aplay with a long audio file, then put the laptop into suspend.
  if it comes back from suspend with working playback, its a JACK issue.
  otherwise, its an ALSA card-specific driver issue.

that's crazy ... I'm only getting errors now, when trying to play
with aplay or alsaplayer (see bottom)

haven't had this errors in the past.
maybe my alsa-version is to new?
although the card is working with jack...
anything wrong with the options?
