Alsa alternative for /dev/dsp

[T o n g <mlist4suntong@yahoo.com>]

Hi,

I'm wondering if there is some easy alternative Alsa devices for 
/dev/dsp. 

The reason I'm asking is that the flash-player in my web browser always 
blocks others to access /dev/dsp. One simple example,

 $ cat /dev/urandom > /dev/dsp
 bash: /dev/dsp: Device or resource busy

I'm wondering if there is an alternative Alsa devices that I can use.

Thanks
