Udev is definitely finding the sound hardware: $ udevadm info -qall -p /sys/class/sound/card0 P: /devices/pci0000:00/0000:00:1b.0/sound/card0 E: DEVPATH=/devices/pci0000:00/0000:00:1b.0/sound/card0 E: SUBSYSTEM=sound E: SOUND_INITIALIZED=1 E: ID_BUS=pci E: ID_VENDOR_ID=0x8086 E: ID_MODEL_ID=0x27d8 E: ID_PATH=pci-0000:00:1b.0 E: ID_PATH_TAG=pci-0000_00_1b_0 E: SOUND_FORM_FACTOR=internal I take it the pulseaudo module-udev-detect depends on 78-sound-card.rules - is there some minimum version I can start from to troubleshoot?
