Hi,
since i updated my gentoo box from kernel 2.6.16 to 2.6.17 all apps
using OSS for sound didnt work. Skype pitched the sound, Firefox had
gaps and so on.
I did some git-bisect to find out what broke my sound and got compile
errors...
Here is what i got to:

- -----------------------------------------------
I'm totaly sure one of this comitts broke the sound because i had some
compile error and copying the whole directory and continued in one with
git bisect bad and in the other with good. So i got two 'solutions' but
i hope at least this can help fix the bug.
If i can do any more for fixing this, just ask.
If this bug is already fixed: I'm sorry, just ignore this mail.

Make sure that you set CONFIG_SND_PCM_OSS_PLUGIN=y in your kernel
config.

If you still have troubles with it, first try ALSA 1.0.12rc2a package,
or try the latest 2.6.18rc tree.

Also, the information about your hardware is defintely necessary for a
proper debugging (unless you figure out that this problem is really
independent from the hardware by testing different environments).
