How to compile the linux without any audio codecs?

Question

I want "no audio" functionality in an embedded system. So, any idea about how to configure kernel without any audio?

Thanks.

Answer 1

1. Use make menuconfig to find the name of the subsystem (in this case CONFIG_SOUND).
2. Create a kernel config fragment containing:

CONFIG_SOUND=n

3. Setup your configuration file with both the default config and the fragment:

make defconfig <NAME_OF_FRAGMENT>

Answer 2

From make menuconfig, disable Device Drivers -> Sound card support, or if you're editing the .config file, prepend CONFIG_SOUND with a #.
