Skype knows nothing about artsd or esd. The reason you see
that message is that the execution of skype is done by
a shell script which checks for the existence of one of
these daemons, and if found, fools skype into using it
via some clever (but not original) subterfuge.
I assume the wrapper was implemented by whoever packaged skype
for gentoo. The library subterfuge seems to have been developed
by the sound daemon developers as a transition aid to allow
legacy OSS apps to be used.
The mechanism involved is to insert a new dynamic linked
library for the interface to the open()/close()/.. etc
system calls, and check every open() call to see if it
is opening '/dev/dsp'. If it is, you replace it with a
sound daemon initialization and intercept all subsequent
I/O on the associated file descripter. All other IO is
passed through to the OS normally.
I have been tinkering with it because I wanted to use skype on
a remote X terminal with networked audio. That requires
intercepting the /dev/dsp I/O for both play and record, and
the full duplex operation is proving tricky.
If you want to see the details of what is going on, look at the
shell script:
% more /opt/skype/skype
#!/bin/bash
#
# Wrapper script to run Skype with sound wrapper when possible
logfile="${HOME}/.Skype/skype.log"
progname="skype"
progpath="/opt/${progname}/"
progopts="--resources-path ${progpath}"
shellcheck1=` which artsshell 2> /dev/null `
shellcheck2=` which esd 2> /dev/null `
artsdcheck=` ps x | grep artsd | grep -v grep `
## We use ps ax for esd as esd can be used globaly for all users.
esdcheck=` ps ax | grep "esd ." | grep -v grep `
skypecmd="${progpath}${progname}.bin"
wrapsound="yes"
.
.
.
You will see it is easy enough to get rid of those annoying messages
if you arn't interested in the sound daemons.
