I built the Kernel with installed in it drivers NOT as modules. The lsmod command gives me the following: # lsmod Module Size Used by Not tainted That's 0 modules I think. Also have not /lib/modules/ ... /kernel/sound directory because I haven't modules, I think. I search in internet and find the following which claims that I must edit the device table in Buildroot configuration: http://elasticsheep.com/2011/01/adding-alsa-audio-support-to-a-buildroot-based-system/ but will try it tomorrow. Is it true any way? Do I need something another special in the config except enabling the ALSA and needed tools from it, as alsamixet? Thanks!
