So I have to Skype with someone, but he is not...well let's just say not a "geek", so I have to log in via SSH to his Fedora machine, and turn on sound [because he can't hear me when using Skype, but I can hear him, so the sound is turned off/too quiet on his side]. How?

You can usually use alsamixer from a command line over SSH to control ALSA sound levels. For a less graphical alternative you can use amixer.

If the system uses OSS instead of ALSA, aumix should do the job.

As a last resort you could use X forwarding to send any other graphical sound control program back to your desktop for control.

ALSA also has amixer, that one is CLI only, without the ncurses TUI. – manatwork Oct 29 '11 at 19:53
A similar alternative for OSS is aumix. – manatwork Oct 29 '11 at 19:59
ssh -C -X user@IPADDRESS gnome-volume-control ?? – LanceBaynes Oct 29 '11 at 20:01
@LanceBaynes Using a graphical mixer over ssh is an overkill and it can only work if the host sshd server has X11Forwarding enabled (which does not seem a good idea in the described scenario). – rozcietrzewiacz Oct 30 '11 at 17:06
