Fix your TouchPad's lost audio
This tip is only for devices running webOS 3.0 and higher
One of the most annoying bugs in webOS 3.0.2 has got to be when your sound just mysteriously just disappears.

In order to accomplish this, you will need access to then command line, which can use access on-device with a homebrew app like Xecutah or if you put your device in Developer Mode and hook it up to PC and use webOS Quick Install.
Once you have access to the command prompt, run these two commands:
You should see an output similar to the screenshot attached and your sound should return, all without the need to reboot your phone
