sometimes fails to load the right codec (or chipset) for audio
Sometimes fails to load the right sound codec (or chipset) for at boot, I think that it's same issue with alsa and OSS.
At boot time (toshiba u300) alsa (or kernel maybe) fails to load sound.
When it works this is loaded:

First I worked around alsa sound state, it doesn't work, then I tried to point my laptop model in «/etc/modprobe.d/alsa-base.conf» file:
options snd-hda-intel model=toshiba

I have to say that before Arch it had installed Ubuntu 10.04 with OSS (problems with keyboard sound keys with alsa), lately before change to Arch I must to restart sound system before it works frequently with this procedure; «soundoff», then «soundon» absolutly freezes the laptop so I had to turn off it and turn on again, then «rm /usr/lib/oss/starting», and last «soundon», then it sometimes works.
Now my only way to have sound is to restart the system time and time again until it works.
Thanks for your advices.

Re: sometimes fails to load the right codec (or chipset) for audio
Maybe two kernel modules that try to control the same piece of hardware, but how can I know what modules are?
Blacklisting [https://wiki.archlinux.org/index.php/Ke … acklisting]
Blacklisting, in the context of kernel modules, is a mechanism to prevent the kernel module from loading. This could be useful if, for example, the associated hardware is not needed, or if loading that module causes problems: for instance there may be two kernel modules that try to control the same piece of hardware, and loading them together would result in a conflict.
Some modules are loaded as part of the initramfs. mkinitcpio -M will print out all autodetected modules: to prevent the initramfs from loading some of those modules, blacklist them in /etc/modprobe.d/modprobe.conf. Running mkinitcpio -v will list all modules pulled in by the various hooks (e.g. filesystem hook, SCSI hook, etc.). Remember to add that .conf file to the FILES section in /etc/mkinitcpio.conf (if you have not done so already) and rebuild the initramfs once you have blacklisted the modules, and to reboot afterwards.

Re: sometimes fails to load the right codec (or chipset) for audio
«Udev loads kernel modules by utilizing... . The inherent disadvantage of this method is that Udev does not always load modules in the same order on each boot.»
Is there a way to know the load order for modules when system has loaded?
Also, from linux.com, «Udev uses the modalias data to find the correct device driver from¬†/lib/modules/`uname -r`/modules.alias.».
Could be something wrong with modalias?
Does someone know a way to manually load Realtek chipset/codec once system has finished loading?
I've been reading about udev rules at freedesktop.org, but I need a newbie howto... :-/
