Bug Description

According to the package description it is supposed to provide ensure compatibility to programs that are still trying to access the old /dev/dsp interface. But it does not do that.

And looking at the list of files provided in the oss-compat package in Precise, how could it? It supplies only a changelog, a license text file, and some directories, nothing else. In short the package seems to be completely useless in Precise. If there is simply no way to supply /dev/dsp in Precise, please remove oss-compat entirely as it serves no purpose then.

As an alternative, start your program with padsp:

oss-compat does install a file, /etc/modprobe.d/oss-compat.conf. The idea is to load the OSS compatibility modules; these are no longer provided in the Ubuntu kernels, so in Precise it's only useful for users who rebuild a kernel with the appropriate configuration (so it's not really useful!).

There are a number of packages which depend on oss-compat so it can't just be removed. What I'd like to do eventually is provide exactly what Dave Lentz describes, although it would require changes to the launchers of the dependent packages...

How about at least changing the package description, so that people are told right away that the package is essentially non-functional?

Unfortunately padsp uses $LD_PRELOAD so it doesn't work with statically linked binaries like some older Linux games - for example, Rilroad Tycoon 2. Backward compatibility matters! Would it be possible to provide a daemon which listens on /dev/dsp and forwards to PulseAudio?

This bug was fixed in the package oss-compat - 3

---------------
oss-compat (3) unstable; urgency=low

  * Use softdep directives in the modprobe configuration. (Closes:
    #660803.)
  * Switch to my Debian address.
  * Use canonical VCS URIs.
  * Drop obsolete Lintian override for module-init-tools dependency.
  * Recommend osspd, which provides OSS emulation using ALSA or PulseAudio
    (LP: #659024, #983707).
  * Standards-Version 3.9.4, no further change required.
