That is esd, Esound daemon.

       esd - The Enlightened Sound Daemon

       Starts up EsounD, which provides a sound mixing server.

       esd [options]

         -d DEVICE     force esd to use sound device DEVICE
         -b            run server in 8 bit sound mode
         -r RATE       run server at sample rate of RATE
         -as SECS      free audio device after SECS of inactivity (-1 to 
         -unix         use unix domain sockets instead of tcp/ip
         -tcp          use tcp/ip sockets instead of unix domain
         -public       make tcp/ip access public (other than localhost)
         -promiscuous  start unlocked and owned (disable authenticaton) 
         -terminate    terminate esd daemon after last client exits
         -noterminate  do not terminate esd daemon after last client exits
         -nobeeps      disable startup beeps
         -beeps        enable startup beeps
         -trust        start esd even if use of /tmp/.esd can be insecure
         -port PORT    listen for connections at PORT (only for tcp/ip)
         -bind ADDRESS binds to ADDRESS (only for tcp/ip)

         -v --version  print version information

       Possible devices are:  /dev/dsp, /dev/dsp2, etc.

FILES /etc/esd.conf           daemon configuration file

And it must be my problem.  It must have been started by default because 
I didn't start it.  I'll see if I can configure it to share the sound 
card or disable it.

Thank you very much.
