removed ATI Radeon card and switched to onboard vga, but same result: no sound:
aplay -l still reports "aplay: device_list:252: keine Soundkarten gefunden ..."

reinstalled ATI card (as before without closed source ATI drivers); no sound, 
but 
the same when starting this bug report:

aplay -l
**** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: HDMI [HDA ATI HDMI], Gerät 3: HDMI 0 [HDMI 0]
  Sub-Geräte: 1/1
  Sub-Gerät #0: subdevice #0

-> ??? the Radeon graphics card has got NO HDMI (only VGA, DVI and composite)
-> only sound device is the onboard chip "Azalia HDA Controller"

Still no sound :-(  
... but not a Ubuntu or Debian Problem: It's ALSA or the Kernel itself. 
Same Problem with Live CDs of Ubuntu based Mint 13, but not Ubuntu based 
Magaeia 2 too.


Any suggestion?  
- 10.04 'til security support ends? And afterwards?
- External sound card (empty PCI Slot available; onboard Sound could be 
switched off)?

I am really frustrated...
