Have I checked the settings? Are you serious? I have stated that it worked fine on my old laptop but there is no sound on the new one ... obviously I have checked the settings ... dozens of times
Please note, if you are rude to members trying to help, they wont bother trying to help in future.
The questions were trying to narrow down your problem to see if we could help or if any other members may have come across the problem. Very often the obvious needs to be eliminated first.
This is also a public forum, so if someone else has this problem, it may be useful to them to try these eliminations too. It may be the answer they were looking for.
