alsa stop working

[lochrist]

I have used Gentoo for 3 years now and I never had any problem with Alsa. Recently I update a few package :

alsa-headers alsa-utils alsa-driver hotplug

and now everything went wrong.

When Hotplugging I get these errors :

* Starting input hotplugging... [ ok ]
* Starting pci hotplugging...

I use kernel 2.4.26-gentoo-r6 with emu10k1 compile as a module. I DON'T have OSS compile (neither in a module or in the kernel).

If I start manually alsa :

$> /etc/init.d/alsasound restart

I get this :
* WARNING: you are stopping a boot service.
* Unloading ALSA...

As you can see I don't have snd-emu10k1. When I modpropbe it I get this error message :

root@foin emu10k1 # modprobe snd-emu10k1
/lib/modules/2.4.26-gentoo-r6/kernel/sound/pci/emu10k1/snd-emu10k1.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.26-gentoo-r6/kernel/sound/pci/emu10k1/snd-emu10k1.o: insmod /lib/modules/2.4.26-gentoo-r6/kernel/sound/pci/emu10k1/snd-emu10k1.o failed
/lib/modules/2.4.26-gentoo-r6/kernel/sound/pci/emu10k1/snd-emu10k1.o: insmod snd-emu10k1 failed

Strange thing is that the file /lib/modules/2.4.26-gentoo-r6/kernel/sound/pci/emu10k1/snd-emu10k1.o exists.

But if I modprobe emu10k1 it works.

It tried to emerge emu10k1 but I get the same result. It is very strange since before that update all things works correctly.

Does someone have an idea to help me? Thanks.

I solve the problem. I just emerge a old version of hotplug and now everything seems to work well.

Still when start alsasound I get :

* WARNING: you are stopping a boot service.
* Unloading ALSA...
* Storing ALSA Mixer Levels
* Unloading modules [ ok ]
* Loading ALSA drivers...
* Using ALSA OSS emulation
* Loading: snd-seq-oss
* Loading: snd-pcm-oss
* Running card-dependent scripts
* Restoring Mixer Levels

I don't understand why it says "Using OSS emulation". OSS is not part of my kernel. How can Alsa decide what driver to use? How it decides to start emulation? It's strange since all my emu10k1 driver are loaded (snd-emu10k1, emu10k1).

I don't have problem right now but if someone understand why with a newer version of hotplug it doesn't work please tell me. If someone understand the OSS emulation thign please explain!
