I was trying the dmix setup on my work computer and I found that I could not work, not even with the default settings, just by trying aplay -Dplug:dmix test.wav gives me nothing.

The card is a Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01). I've noticed in the status proc entry that the application pointer stays always at 0.

Any ideas or suggestions?

Francisco

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      : 209136

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..
