Took your advice, e1sunz, uninstalled FFxp patch and FF7 and deleted directory. Did full install, unselected all three in-install drivers, did 1.02 patch, followed up by Aali's 0.7.10. No in-game sound effects for me for every combination of Aali's 0.7.5, 0.7.8, 0.7.10 and 0.7.11 patchs, with and without compatibility mode, choosing Software renderer or Custom driver, with and without logarithmic control, full Administrator access with the only concession being the isos may or may not be mine.
Kompass, the in game controls for music are at 10 and sound effects 100. Wave volume control is on, nothing muted in sounds options.
However the Aali's 0.7.11 combo yielded a dialog box along the lines of OpenGL being Microsofts software renderer, Expect extreme lag. And Compatibility mode and 0.7.10 made FFConfig and FF7.exe refuse to come up.
Continually infuriating, I'm going to hurl something into space
