I cannot get my laptop to produce any sound under 10.3. However, it

Just to follow up: I noticed some suspicious messages in my dmesg output:
ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 5
PCI: setting IRQ 5 as level-triggered
ACPI: PCI Interrupt 0000:00:1f.3[B] -> Link [LNKB] -> GSI 5 (level, low) ->
IRQ 5
ACPI: PCI Interrupt 0000:00:1f.5[B] -> Link [LNKB] -> GSI 5 (level, low) ->
IRQ 5
ACPI: PCI interrupt for device 0000:00:1f.5 disabled
The device 00:1f.5 is the sound card, according to lspci.
Does this mean that I have some kind of IRQ conflict? I tried to reboot
with ACPI turned off, but that didn't seem to change anything.

Try booting with APIC (Advanced Programmable Interrupt Controller)
turned off _not_ ACPI. At boot, enter "noapic nolapic". noapic is just
"no apic" nolapic is "no local apic".
