Fedora development currently ships kernel-2.6.8-1.584 (including
alsa-driver 1.0.4) and alsa-lib-1.0.6-1. This causes - at least -
applications to use the wrong device (/dev/snd/pcmC0D2p) for AC3
passtrough with emu10k1 based soundcards.
Is this something that needs provides or conflicts at the kernel
this sounds really broken.
This means that the device descriptions in /usr/share/alsa from
alsa-lib do not necessarily match the devices provided by the kernel
driver if the versions do not match.
I would suggest to provide alsa-driver in the kernel and require the
matching version from alsa-lib.
that sooooooo sounds the wrong thing. Very very wrong.
You don't want half your userland to go up or down depending on which
exact kernel you boot.
I think 2.6.8-1.584 does have the 1.0.6 kernel updates. This was
incorporated from the bk-alsa.patch sometime ago.
Uhm, I think Sammy is right, I have found "Advanced Linux Sound
Architecture Driver Version 1.0.6 (Sun Aug 15 07:17:53 2004 UTC)." in
Coming back to this; if ALSA 1.0.6 is in the kernel, where is the
problem coming from?
I have been using a stock 188.8.131.52 kernel, not the Fedora supplied and
patched one, but the problem persists, you need to downgrade alsa-lib
if you boot an old kernel.
This isn't really solvable in this context. We can't randomly change
libraries depending on which kernel you boot. Hence, we just have to
make sure that the library stays current with the drivers in the kernel.
(And possibly get a sane release model from upstream... oh well.)
