I've had OSS v4 installed for 2 days. When I tried to launch its mixer, it said "no mixers are available", or "no mixers found". Bottom line: ossxmix was not installed.
So I uninstalled OSS v4. I then followed the official Ubuntu documentation (help.ubuntu.com) and removed ALSA and installed some stuff related to OSS v4 (under the prerequisites category in the help document). I then installed OSS v4 using the mercurial repositories. That also installed ossxmix. I then saw that there was no Production option available under 'src', in the mixer, so I found this guide: http://www.opensound.com/forum/viewtopi ... 730#p14690
It did let me choose the Production option, but now I have no sound at all, and ALSA is gone as well (not that I'm willing to revert back to it). Before recompiling OSS v4 with Production src enabled, I did have sound using OSS v4. I should mention that I now have no sound at all, no matter the src I use. Strangely enough, the mixer does show activity when I play a video or music.
Does anyone have any idea how to fix this? Maybe an explanation on how to completely remove OSS v4, so that I can completely reinstal it from scratch, would work.
Thanks in advance.

I hope someone here knows what it means.
Edit 2: I've reinstalled alsa-utils, so now I can access System>Preferences>Sound (using Ubuntu). Apparently, no hardware appears under the Hardware tab. Also, Dummy Output is the only output available.
Before I messed with my OSS installation, both my built-in Realtek sound chipset and my ESI Juli@ card appeared. They are both gone now. So it seems that OSS v4 is installed fine, as far as I know, but Ubuntu no longer recognizes my hardware. I hope this helps identifying a solution.
Edit 3: I've installed some missing... umm... thing, and now ALSA works, but OSS does not. When ALSA is used, my ESI Juli@ is identified and appears under the Hardware tab of Sound, but not when OSS is used.
