    considering that alsa API and drivers is pretty stable i see no problem
    in OSS removal.
    When writing a program adding oss compatibility seems faster, but,
    creates lots of problems.
    check the skype example (yes i know it's closed-source). 99% of sound
    problems users have is due to OSS driver usage.

    that's a big problem. Needs a radical solution. Considering aoss works
    in 50% of cases i suggest aoss improvement and not OSS keeping in kernel.

    A good idea could be an OSS API layer over Alsa-lib...but i personally
    don't know how much can that costs, considering you should link against
    alsa-lib too.

    This discussion seems a no-sense.
    Kernel API continues to change every -rc and noone cares that.
    OSS has been deprecated for a lot, and it's as old as moon.
