Module not found despite existing on filesystem & alias existing


I have a problem concerning the snd-usb-caiaq module. It exists on my drive as:

-rw-r--r-- 1 root root 19979  5. Nov 06:05 /usr/lib/modules/3.6.6-1-ARCH/kernel/sound/usb/caiaq/snd-usb-caiaq.ko.gz

And lines containing snd_usb_caiaq exist in /usr/lib/modules/3.6.6-1-ARCH/modules.alias:

[root@lillassea 3.6.6-1-ARCH]# cat modules.alias | grep caiaq
alias usb:v17CCp0808d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp041Dd*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCpBAFFd*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp2305d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp041Cd*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp0839d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp0D8Dd*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp1915d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp1978d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp0815d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp4712d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp4711d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp1940d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq
alias usb:v17CCp1969d*dc*dsc*dp*ic*isc*ip*in* snd_usb_caiaq

However, when I attempt to display the module's info, I receive a message explaining the alias is not found:

[root@lillassea 3.6.6-1-ARCH]# modinfo snd_usb_caiaq
ERROR: Module alias snd_usb_caiaq not found.

modprobe fails without any explanation, and lsmod contains nothing about caiaq. I tried "modinfo snd-usb-caiaq" on a whim, but again nothing happened.

Re: Module not found despite existing on filesystem & alias existing

Presumably you're still using 3.6.5-1-ARCH and haven't rebooted yet.
