Subwoofer and whole volume controls are linked

[Shunsuke Akagi]

Under System Settings->All Settings->Sound, this is an interface problem.
I suspect it would happen on any sound card or condition as long as mode is with subwoofer.
When I slide volume control bar under any x.1 mode in the sound setting, subwoofer volume would change.
When I slide subwoofer volume, whole volume would change.

do you mean 5.1/7.1 or you have 2.1 or 4.1 speakers ?

do your driver have a volume control for the subwoofer ?

It does not matter. As long as x.1 that is with subwoofer, it would happen.
It is simple graphic interface issue.
If you have x.1, choose x.1 then move subwoofer sliding volume controls or whole volume control.
You will see strange moves of sliding volume would happen.
