I've found, that the problem was caused by buggy crosscompiler,
compiling with native compiler solved the problem disappeared.

But there is another problem: when I connect headphones the sound
becomes wery quiet and it souns as if it was strongly compressed. When
I detach headphones it sounds good again. This is true for bouth my,
and Vincent Bénony's kernels, bouth my PDA's and two different pairs
of headphones.
