No, AFAIK this is for oss!
I have absolutely *no* /dev/dsp# available!
What the fine manual says is:
=============
alsa
ALSA 0.9/1.x audio output driver.
mmap
Sets experimental mmap‐mode (does not work for more than
2 channels).
noblock
Sets noblock‐mode.
device=<device>
Sets the device name. Replace any ’,’ with ’.’ and any
’:’ with ’=’ in the ALSA device name. Make sure you do
not set this when you want hwac3 output via S/PDIF, un‐
less you really know how to set it correctly.

I already fell on that trap and the scars still show :) :)
