[pulseaudio-discuss] Missing second HDA playback device

Sun Jan 18 07:22:35 PST 2009

I definitely have two playback devices:

jonsmirl at terra:/etc$ hal-device | grep playback
28: udi = '/org/freedesktop/Hal/devices/pci_8086_284b_alsa_playback_1'
  info.udi = '/org/freedesktop/Hal/devices/pci_8086_284b_alsa_playback_1'
 (string)
  alsa.type = 'playback'  (string)
29: udi = '/org/freedesktop/Hal/devices/pci_8086_284b_alsa_playback_0'
  info.udi = '/org/freedesktop/Hal/devices/pci_8086_284b_alsa_playback_0'
 (string)
  alsa.type = 'playback'  (string)
jonsmirl at terra:/etc$

playback_0 is analog out
playback_1 is SPDIF out

module module-hal-detect does not load the second one.

I can force it to load manually and it works....
