[gentoo-user] I have two sound cards - and no sound

[the...@sys-concept.com]

On my new box I seem to have two sound cards but no sound.

cat /proc/asound/cards

HDA ATI SB at 0xfe400000 irq 16
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe080000 irq 50

What am I missing?
Doesn't matter which card I select via "alsamixer" I get:

" This sound device does not have any controls."

You are missing the correct sound driver for your hardware.

You could use Google to find out which kernel module is required for your
hardware; or, quicker and potentially more accurate would be to set up *every*
driver as a module in your kernel and reboot. The correct module will be
loaded and will show up in dmesg and lsmod. Then you can deselect the rest
and rebuild your kernel.

Or you can boot from a live CD that works with your sound card and see
which modules it uses for it, using dmesg and lspci -k. That saves
rebuilding your kernel again.

What do you have when you have six lawyers buried up to their necks in
sand? Not enough sand.

For clarity, you are missing the correct CODEC drivers.

I booted from live USB since it was a quicker method and:
"dmesg |grep -i codec" showed me:
CONFIG_SND_HDA_CODEC_REALTEK

Thank you all it was a quick solution.
