hi, i'm just here to chime in with "me too".. aplay -Dplug:dmix test.wav produces..

tapas@mango:~$ cat /proc/asound/card0/pcm0p/sub0/status 
state: RUNNING
trigger_time: 1088212367.335582000
tstamp      : 1088212371.692661000

hw_ptr grows and grows and grows.. appl_ptr stays at 0

tapas@mango:~$ cat /proc/asound/card0/pcm0p/sub0/status

the equivalent happens for arecord -Dplug:dsnoop

wicked.. aplay and arecord don't complain.. they sometimes even produce an xrun.. allaround very normal playback behaviour except for the fact that the sound never reaches the speaker..
