|I need to be clearer: only audio problem is that cannot access expanded volume control: line in, wave out, etc. Can access main output volume and rest of Sounds and Audio devices control panel. |
In Audio, Voice, all Volume buttons do nothing.
In Volume, Advanced does nothing.
Just did Dell Diagnostics in boot partition all A-O.K.
How about if I uninstall Soundmax, reboot so Windows audio is now discovered hardware and install it instead.
