On one of my test boxes with the ATI chipset (SB600 south bridge) there's no
sound output.  Bisection shows that the following commit causes this to happen
and reverting the commit fixes the problem for me:

commit cf97e6678f1e1e7bbdb566c36771540123832a31

    ALSA: hda - Fix wrong volumes in AD1988 auto-probe mode
    
    Don't create mixer volume elements for Headphone and Speaker if they
    use the same DAC as normal line-outs on AD1988.  Otherwise the amp
    value gets screwed up, e.g.

Please let me know if you need any additional information.
