    what model of laptop is this ? and do you know what motherboard
 revision is involved, what behaviors do you get on another OS say windows
 where the audio is well supported ?

    It would help in diagnosing the problem. you do get sound now however
 correct ?this could be a hardware design issue.

    here is the chipset pdf. I am trying to see how many audio layouts one
 could generate with such a chip. its likely the output may all be
 internally connected and there is additional control implementation on the
 chipset to configure which audio circuts are active.

     thats the datasheet

    white paper briefing describing chip capabilitys.

    its entirely possiable depending on how the implemented certain
 features on teh chip that the oss driver doesn't fully support your MB
 layout.
