name of sound device file?

[D. R. Evans]

I am trying to run the "cw" program for sounding out Morse code. By
default, it writes its output to the sound device /dev/audio (see "man cw").

But on my 64-bit natty system there is no /dev/audio file:

----
[HN:cw] cw
cw: cannot set up soundcard sound
/dev/audio: No such file or directory
----

So what should I pass with the -x option to change the device name? I have
tried /dev/mixer and /dev/console as suggested on the man page, with no luck:

----
[HN:cw] sudo cw -x /dev/mixer
cw: cannot set up soundcard sound
/dev/mixer: No such file or directory
[HN:cw] cw -x /dev/console
cw: cannot set up soundcard sound
/dev/console: Permission denied
[HN:cw] sudo cw -x /dev/console
this is a test
cw: ioctl SNDCTL_DSP_SETFRAGMENT: Invalid argument
tcw: ioctl SNDCTL_DSP_SETFRAGMENT: Invalid argument
hcw: ioctl SNDCTL_DSP_SETFRAGMENT: Invalid argument
cw: ioctl SNDCTL_DSP_SETFRAGMENT: Invalid argument
cw: ioctl SNDCTL_DSP_SETFRAGMENT: Invalid argument
...
