Hi Jaime,

In a functional default Ubuntu install, esd is enabled, and because esd is configured to use 
ALSA's OSS emulation (/dev/dsp), aplay will block (it will appear to hang); the default device is 
already in use. 
 
If you pkill esd, you will be able to use aplay.

You can use aplay if dmix is configured or if esd has released /dev/dsp.
