edit the file to comment out the following lines like this

#load-module module-udev-detect
#load-module module-detect

add the following lines immediately following the ones you commented out

load-module module-alsa-sink device=hw:<your_card>,<sink_index> sink_properties="your_sink" load-module module-alsa-source device=hw:<your_card>,<source_index> source_properties="your_source"

You can discover the value for <your_card>, <sink_index> and <source_index> via `aplay -l` and `arecord -l`

restart pulseaudio
`pulseaudio -k`

verify it worked
`pactl list sinks`
`pactl list sources`

Not a fix but it is a workaround

Thanks, but it doesn't really work for me. `aplay -l` shows:

card 0: D2X [Xonar D2X], device 0: Multichannel [Multichannel]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: D2X [Xonar D2X], device 1: Digital [Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

so the D2X (analog output) should be "hw:0,0", right? Adding this line:

load-module module-alsa-sink device=hw:0,0

does not add a D2X sink to `pactl list sinks`. Adding this line:

load-module module-alsa-sink device=hw:0,1

does add D2X *digital* ouptut sink. So PulseAudio has a specific problem with multichannel (5.1) analog output for some reason.
