emu/validity.cpp, ui/info.cpp: Base "no sound" check on speaker devices.
Currently the speaker device is the only way sound can get to the OSD
layer, so its presence or absence determines whether the emulated system
is capabale of producing sound. A few systems use chips with sound
capability for other purposes (typically I/O or video) while leaving the
sound outputs disconnected. These systems should display the notice
about the absence of sound output.
