I am currently using a SB0790 (SoundBlaster X-Fi Xtreme) card and am using 3 x analog stereo output channels for a multi-zone audio system.

I need to find a PCIe based card that offers the same 3 or 4x separate analog stereo outputs rather than digital 5/6/7.1 outputs.
The Xonar DX has analog 7.1 outputs.

And they are independent output devices?  Meaning, that I can assign MPD outputs to each pair separately?

For example, here is what I currently see with the existing SB0790 card:


$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: CA0106 [CA0106], device 0: ca0106 [CA0106]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: CA0106 [CA0106], device 1: ca0106 [CA0106]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: CA0106 [CA0106], device 2: ca0106 [CA0106]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: CA0106 [CA0106], device 3: ca0106 [CA0106]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: Intel [HDA Intel], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


And the MPD configs look like this:

audio_output {
    type    "alsa"
    name    "XFi Zone1"
    device  "hw:CA0106,0"
    format  "44100:16:2"
}

audio_output {
    type    "alsa"
    name    "XFi Zone2"
    device  "hw:CA0106,1"
    format  "44100:16:2"
}


etc.

Many Thanks.
