I have a customer who says that mplayer (using OSS) does not work when he tries a kernel based on 2.6.23-rc4, but it works when he uses a kernel based on 2.6.21. Everything else is the same (including the version of alsa-lib), so I presume something broke in the OSS emulation in the kernel.
It could also be a change in the driver.
And it would be nice to know what "does not work" actually means.
Is it possible to back-level the ALSA support in the kernel itself?
The alsa-kernel tree is only compatible with the current development kernel.
The alsa-driver package works with older kernels, but must be compiled seperately.
Can I just download ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.XX.tar.bz2 and follow the instructions in the INSTALL file?
Yes.
If you update the kernel, are you supposed to use the latest alsa-lib as well?
No; the kernel and lib versions are more or less independent.
