As posed I don't know that the question is answerable. You don't state |
| 55 |
what desktop environment you are using. If it happens to be KDE |
| 56 |
then you will likely need to dig into pulseaudio through the System |
| 57 |
Settings GUI which could be the controlling feature in that |
| 58 |
environment. |
| 59 |
|
| 60 |
Any other desktop environment I have no experience these days. |
| 61 |

Good luck, |
