I changed it like yours, now (after recompiling kernel), my sound card is also sbc1:
sbc1: <ESS ES1869> at port 0x220-0x22f,0x388-0x38b,0x330-0x331 irq 5 drq 1,0 on
isa0
pcm1: <ESS 18xx DSP> on sbc1

> All of my sounds work well.  Have you, in /dev/, sh MAKEDEV snd0?

Yes I had.
And I did it this time also, but: Can not open /dev/dsp, so I tried sh MAKEDEV snd1 and it worked.

But still having that problem. Probably I have not explained it clearly. The sound card works. I do mpg123 some.mp3 and it plays. But when I start to copy any file (like cp any.big.mpg /archive), I'm not only hearing the some.mp3 sound, but also a lot of *unwanted* sound. It seems to me like the sound card also plays the data I am copying. I am not sure, but probably the problem is in DMA transfer or in some IRQ setting (i don't know what exactly DMA and IRQ means).

sbc1: <ESS ES1869> at port 0x220... irq 5 drq 1,0 on isa0
                                          ^^^^^^^
Can not this be the problem? Like some in some output from dmesg from other people I have only seen one number.

And I have also found some funny line in logs: 
Jun 12 09:37:47 ivetka /kernel: stray irq 7
