Title:
  Due to lack of OSS kernel modules, have to recompile the kernel to
  enable sound in old games - aoss/padsp do not work

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've had this issue since about 12.10 or whenever the oss modules with
  disable in the kernel.

  i.e

  CONFIG_SND_MIXER_OSS
  CONFIG_SND_PCM_OSS
  CONFIG_SND_PCM_OSS_PLUGINS

  Ubuntu is one of the few distros to take out these module from their
  kernel builds.

  On Debian, Fedora, Arch and Opensuse the modules are in the kernel
  (you usually have to manually load them (i.e they are present by
  default wbut disabled - with ubuntu the modules are actually removed.)

  There is one game in particular I play, it in an old obscure game
  called paintball2 - http://digitalpaint.org/

  It uses OSS by default - it does have an SDL option too (which works
  in ubuntu) - but the SDL plugin is buggy.

  With all other distros I can just manually load the OSS modules, with
  Ubuntu I have to recompile the kernel in order to have OSS sound.

  Could we not change the policy and include the modules (the size
  difference will be basically none.) so at least people have the option
  to use them without the hassle to recompiling the kernel - its a PITA
  having to do it again each time there is an update.

  I know of aoss and padsp - these tools do not work (at least with this
  game), they never have in multiple machines (all have had intel HDA
  cards)

  i.e

  -------------------------------------
  aoss ./paintball2

  LoadLibrary("./snd_oss.so")
  /dev/dsp: Invalid argument
  SNDDMA_Init: Could not mmap /dev/dsp.
  -------------------------------------

  --> no sound

  -------------------------------------
  padsp ./paintball2

  Paintball 2 -- Version 2.0
  execing configs/config.cfg
  Console initialized.

  ------- sound initialization -------
  LoadLibrary("./snd_oss.so")
  SNDDMA_Init: Sorry, but your soundcard doesn't support trigger or mmap. (00005100)
  -------------------------------------

  --> no sound.

  As soon as i recompile the kernel and add the modules it works fine.

  How can I get the modules re-added - there is no harm having them in
  the kernel but disabled on startup...
