Hi,

>I wonder whether it is possible with ALSA, in simple questions:

yes.

>Is there such a thing?  Where to get it from
ld10k1 - not yet finished, but something works (many bugs)
http://ld10k1.sourceforge.net
Mostly tested on Audigy (somehow works on SB Live too), has problem 
to run on gentoo - probably bug in ld10k1.

>If not, is there a kind of API for writing such utility?
Use alsa HWDEP interface and look at alsa-
driver/alsa/kernel/include/emu10k1.h

struct emu10k1_fx8010_tram_t;
struct emu10k1_fx8010_pcm_t;

IOCTLS:
SNDRV_EMU10K1_IOCTL_INFO
SNDRV_EMU10K1_IOCTL_CODE_POKE
SNDRV_EMU10K1_IOCTL_CODE_PEEK
SNDRV_EMU10K1_IOCTL_TRAM_SETUP
SNDRV_EMU10K1_IOCTL_TRAM_POKE
SNDRV_EMU10K1_IOCTL_TRAM_PEEK
SNDRV_EMU10K1_IOCTL_PCM_POKE
SNDRV_EMU10K1_IOCTL_PCM_PEEK
SNDRV_EMU10K1_IOCTL_STOP
SNDRV_EMU10K1_IOCTL_CONTINUE
SNDRV_EMU10K1_IOCTL_ZERO_TRAM_COUNTER
SNDRV_EMU10K1_IOCTL_SINGLE_STEP
SNDRV_EMU10K1_IOCTL_DBG_READ

In recent alsa version SB Live is started in analog mode (I hope)

You can assign any alsa control to any oss control 
(through /proc/asound/card/oss_mixer file) and you can rename any 
alsa control on Live using HWDEP layer
