This is really strange. Sound used to work on my laptop, now it is just -- 
gone. The hardware hasn't changed (obviously):

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
        Subsystem: Toshiba America Info Systems Device ff08
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- 
Stepping- SERR- FastB2B- DisINTx-
        Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- 
<TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 64, Cache Line Size: 32 bytes
        Interrupt: pin A routed to IRQ 10
        Region 0: Memory at f8700000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA 
                Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME-

but, there is NO /sys/module/snd -- Huh?

[01:06 alchemy:~] # lsmod|grep '^snd' | column -t
(returns nothing, there are no snd modules at all)

Further, there is no sound dev:

[01:06 alchemy:~] # l /dev/snd

 I've been throught the alsa wiki and it is still gone. I've tried adding the 
right module, but it isn't even on the system anymore:

[17:21 alchemy:/etc/modprobe.d] # modprobe snd-hda-intel
FATAL: Module snd_hda_intel not found.                  

[17:45 alchemy:/media/disk/david] # modprobe snd_hda_intel
FATAL: Module snd_hda_intel not found.

Additinally, KDE prompts me to delete removed sound device HDA ATI SB, ALC268 

Running SuSE 11.2 on the same box (different hard drive) shows the following 
modules are configured for sound (works fine):

08:39 alchemy:~/.kde4/share/config> lsmod | grep snd
snd_pcm_oss            60032  0
snd_mixer_oss          22728  1 snd_pcm_oss
snd_seq                78528  0
snd_seq_device         10460  1 snd_seq
snd_hda_codec_realtek   317868  1
snd_hda_intel          37088  2
snd_hda_codec         111112  2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep              11216  1 snd_hda_codec
snd_pcm               117808  3 snd_pcm_oss,snd_hda_intel,snd_hda_codec
snd_timer              32152  2 snd_seq,snd_pcm
snd                    97608  14 
snd_page_alloc         12600  2 snd_hda_intel,snd_pcm

Here is the hwinfo output from the suse install:

Now how do I get the sound to re-appear in Arch??
