It looks > correct to me on my machines: My machines and the fedora rawhide machines using the 2.6.20-rcX releases look nothing like what you pasted. If they did, hald would be working... (I'll note that bugs have also been logged against Pulse and HAL by users having trouble, so it's not just us.)

That is a vanilla 2.6.20-rc5 build on a fedora rawhide machine, the rawhide-tweaked kernel and 2.6.19-rc6-mm2 produces the same results. With my patch, at least the 'old' entries for the pcm devices are as before (The patch doesn't 'correct' anything for the device types other than pcm and control, adsp and audio are still messed): /sys/class/sound/ |-- adsp | |-- dev | |-- device -> ../../../class/sound/card0 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- audio | |-- dev | |-- device -> ../../../class/sound/card0 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- audio1 | |-- dev | |-- device -> ../../../class/sound/card1 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- card0 | |-- 0-0:AD1981B | | |-- bus -> ../../../../bus/ac97 | | |-- power | | | `-- wakeup | | |-- subsystem -> ../../../../bus/ac97 | | `-- uevent | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- power | | `-- wakeup | |-- sound:adsp -> ../../../class/sound/adsp | |-- sound:audio -> ../../../class/sound/audio | |-- sound:dsp -> ../../../class/sound/dsp | |-- sound:mixer -> ../../../class/sound/mixer | |-- subsystem -> ../../../class/sound | `-- uevent |-- card1 | |-- 1-1:unknown codec | | |-- bus -> ../../../../bus/ac97 | | |-- power | | | `-- wakeup | | |-- subsystem -> ../../../../bus/ac97 | | `-- uevent | |-- device -> ../../../devices/pci0000:00/0000:00:1f.6 | |-- power | | `-- wakeup | |-- sound:audio1 -> ../../../class/sound/audio1 | |-- sound:dsp1 -> ../../../class/sound/dsp1 | |-- sound:mixer1 -> ../../../class/sound/mixer1 | |-- subsystem -> ../../../class/sound | `-- uevent |-- controlC0 | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- controlC1 | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.6 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- dsp | |-- dev | |-- device -> ../../../class/sound/card0 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- dsp1 | |-- dev | |-- device -> ../../../class/sound/card1 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- mixer | |-- dev | |-- device -> ../../../class/sound/card0 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- mixer1 | |-- dev | |-- device -> ../../../class/sound/card1 | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D0c | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D0p | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D1c | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D2c | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D3c | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC0D4p | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.5 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC1D0c | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.6 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- pcmC1D0p | |-- dev | |-- device -> ../../../devices/pci0000:00/0000:00:1f.6 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- seq | |-- dev | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- sequencer | |-- dev | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent |-- sequencer2 | |-- dev | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent `-- timer |-- dev |-- power | `-- wakeup |-- subsystem -> ../../../class/sound `-- uevent Monty
