Hi Tony and Welcome to LQ!
If you want some help you need to give a bit more info about your system.
1. What sound card are you using?
2. What sound system are you using? Alsa? Pulse? OSS?
3. Have you checked your mixer to make sure that nothing is muted?
4. Have you checked LQ for people with problems similar to yours (and the solution
)?
5. Try not to use phrases like "have tried so much". These don't give us any information.
cheers,
jdk
