I've installed 0.90.0.3 on debian with alsa and alsa-oss. It executes fine, registration worked,chatting works.
But when I click that green phone to call a contact in the contacts list, skype shows 'hugowww failed'.
Meanwhile, my terminal shows as below:


UI: CallManager: callTo : hugowww
MainForm: newCallTab
Sky: Call: getStatus routing
SingleCallManager: SingleCallManager
Engine: getUser() : hugowww
UI: User::getAvatar loading avatar

What can I do?

I can see this:


Some other application is probably blocking your sound device so Skype can't open it and the call fails. Close your mp3 player, maybe shut down sound daemons, etc. and try again.

You can see the list of process PIDs using /dev/dsp by running

If you can't find anything try to do that as root.

I had to kill my esd process, which means no sound on the gnome desktop !

$ man esddsp

and create a wrapper script for Skype ...
