/dev/audio

[Mary Honeycutt <mkhoney@bellsouth.net>]

Hi,

  I'm receiving messages in .xsession-errors, stating:
"sox: unable to open /dev/audio.  Device or resource busy."

  All sounds still play, however, everytime a sound file is run, 
a new error msg is generated.

  How can I find out what is using /dev/audio?

Thanks,

MaryK
