According to this bug report (or feature request), all OSS support in Maverick Meerkat (10.10) was removed. This means that a lot of programs which are included in the base Ubuntu install do not work out of the box – and may never work if they are not updated. For some odd reason, this removal of OSS did not make it into the release notes for Ubuntu 10.10.
It appears that Debian has not removed OSS.
The removal of OSS by the Ubuntu team was continually refered to as part of “cleaning up the audio mess”; one person created a large graph of the Linux audio subsystems – which shows the complicated layout of all of the Linux audio possibilities.
There are numerous programs (in Ubuntu repositories and outside) that this affects, including:
- Enemy Territory
- Unreal Tournament 99
- XSquawkBox plugin for X-Plane
- Audacity (if using OSS)
- CMU Sphinx (PocketSphinx)
- Sniper Elite
- VLC (if using OSS)
These are just the ones that I could track down; there almost certainly dozens of others. Unfortunately, the removal of OSS was done without notification to users or developers, and the general response is that the programs are broken if they use OSS. This means that Ubuntu Maverick Meerkat was shipped with programs that had no audio because of missing OSS support.
This is no way to create a distribution. The only fix is to revert the “fix”: compiling your own kernel with OSS support. If you do this, you’ll also want to pin the version to the one installed so APT doesn’t try to overwrite your version with a new kernel without OSS support. There is a good tutorial that shows you how to compile your own Ubuntu kernel.
