[PlanetCCRMA] Alsa and frames size

[Mark Knecht]

Probably because your card doesn't support it.

For instance, the RME cards will support buffer sizes as low as 64, but they
won't support anything other than 2 periods. All these cards are different
and, unfortunately, no one has really thought to update the Alsa site to
have a nice table of what parameters each card can accept. That would be
pretty cool, really...

  Hi all,

  Why can't I start jack with less than 512 frames per period?

----------------------------------------------------------------------------

  loading driver ..
  creating alsa driver ... hw:0|hw:0|256|2|48000|0|0|nomon|swmeter|rt|32bit
  control device hw:0
  configuring for 48000Hz, period = 256 frames, buffer = 2 periods
  Couldn't open hw:0 for 32bit samples trying 16bit instead
  ALSA: cannot set period size to 256 frames for capture
  ALSA: cannot configure capture channel
  cannot load driver module alsa

  Can't find anything on that in the archives and you guy's all seems to be
able to set the frames as low as 64!

  Starting Jack with qjackctl. Soundblaster live! with the latest planet
kernel on RH9.

  Thanx!
