  Hi all,

  Under SuSE 8.0 I have these lines on my ~/.asoundrc:

  pcm.cmipci {
          type hw
        card 0
        device 2
  }

  ctl.cmipci{
          type hw
        card 0
  }

  as Takashi suggested to me some time ago, and I run jack version 0.40;
  With these settings I'm able to start jackd: playing and recording
  with ardour is working. Instead, on a Red Hat 8.0 with Planet CCRMA
  and jack 0.44 with the same .asoundrc I get:

    [emillo_AT_redmillo emillo]$ jackd -d alsa -d cmipci
    jackd 0.44.0

    ALSA: mmap-based access is not possible for the playback stream of
    this
    audio interface
    ALSA: cannot configure playback channel
    cannot load driver module alsa

  And this is preventing me to record with ardour, since the only input
  available on the Midiman DiO 2448 is the spdif (hw:0,2).
  
  How can I work around this issue ? It's jack or alsa related ?
  Maybe I can define something smarter on .asoundrc that let me use
  spdif for recording and normal analog out to playback ?
  
  Thank you all in advance.
  Best regards
