After a reinstall, I have no sound on my RPI2b . Troubleshooting revealed I don't have "snd_bcm2835".
$this->bbcode_second_pass_code('', 'modprobe snd_bcm2835
modprobe: FATAL: Module snd_bcm2835 not found in directory /lib/modules/5.4.51-2-ARCH
')
The wiki states:
$this->bbcode_second_pass_quote('', 'a')lsa-utils should supply the needed programs to use onboard sound.
[fixed, my mistake] no sound: no snd_bcm2835

[fixed, my mistake] no sound: no snd_bcm2835

I do have alsa_utils:
$this->bbcode_second_pass_code('', 'pacman -Q | grep alsa
alsa-lib 1.2.4-3
alsa-topology-conf 1.2.4-2
alsa-ucm-conf 1.2.4-2
alsa-utils 1.2.4-2')
How can I find the package that contains snd_bcm2835?
Running "pacman -F snd_bcm2835" listed no package ...

Firstly, the module you seek contains a dash not an underscore so you need to adjust your query. To answer your question, you can use pacman -F but it is slow. You also need to include a -x to make the search a regex. I recommend using pkgfile instead which is much faster.

I am more concerned that your system wants to look for modules in that old location. Suspect you updated the system which pulled down a new kernel but you have not rebooted.
