Is it possible to play >1 sound stream?

Hi! I have freebsd 10. I am using it as desktop system.
Everything is good, but idk why 2 or more programs cant play audio at same time.
When second program starts playing audio - first program simply interrupts.

Playing around
Code: 
dev.pcm.0.play.vchans
dev.pcm.0.play.vchanmode
dev.pcm.0.play.vchanrate
gives 0 effect.

What should i do?

Maybe install OSS4? But after installing and enabling OSS4, pulseaudio (some programs need it) simply doesn't work...

Tnx a lot.

UPD:
Code: 
$ cat /dev/sndstat

Does "playing around" mean you followed 8.2.4. Utilizing Multiple Sound Sources?

no
Code: 
$ kldstat
Id Refs Address            Size     Name
 1   31 0xffffffff80200000 15f03b0  kernel
 2    1 0xffffffff818ac000 dfb0     snd_envy24.ko
envy24 is a chip, which is used for many sound cards. One of them i have: M-audio audiophile 2496. snd_envy24.ko is a driver for this card.
