First must tell you that want to use sound only with WAV files!
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:

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!
