Flash 没有声音的解决

The problem is that Flash is old and doesn't support Ubuntu's directory structure for esd properly. It wants to use /tmp/.esd/socket for the sound connection. But Ubuntu uses /tmp/.esd-/socket for the sound (the uid for the user that installed Ubuntu is 1000). A quick hack you can do to fix this is to symbolic link that directory. To do that, go to System - Preferences - Sessions - Startup programs and add
ln -s /tmp/.esd-1000 /tmp/.esd
