LOST ALL AUDIO

Since installing Audacity, I’ve lost all audio on my PC… help…
I’m using Windows XP and Audacity version 2.0.0 which I’ve upgraded via download to 2.0.6

If you are using a USB audio device, see here: http://manual.audacityteam.org/o/man/faq_playback.html#usb

Also, please be careful using Windows XP. Microsoft no longer support it, which makes it a dangerously insecure operating system.
