As I mentioned in my original post it’s a Realtek device and driver.
Device status in the Device Manager is, “This device is working properly.”
The last event in the device properties for it is, “Device started”
The information listed for that event is,
"Device INTELAUDIO\FUNC_01&VEN_10EC&DEV_0245&SUBSYS_103C8B8F&REV_1000\5&26816dff&0&0001 was started.
Driver Name: oem196.inf
Class Guid: {4d36e96c-e325-11ce-bfc1-08002be10318}

It’s labeled in the Windows 10 volume/device selection in the task bar and in FxSound as “Speakers (Realtek (R) Audio)”
If I play sounds the Windows “App volume device preferences” and FxSound shows a graphical representation of the sounds varying, but there is no sound from the speakers.
When I turn off FxSound with it’s power button on it’s interface, I still cannot select the Realtek sound device in the Widows volume control or in “App volume device preferences”, FxSound instantly takes it’s place. Is that how it’s supposed to operate even with FxSound in “off” mode??!!! FxSound should allow COMPLETELY bypassing it when it’s not desired!
I can only conclude than FxSound is intercepting the output from this driver, sound device and there’s something broken in FxSound so it never gets out of the FxSound virtual audio device?
Every indication is the Realtek device, drivers, physical speakers are working, BUT THERE IS SIMPLY NO SOUND FROM THE SPEAKERS. Again, as I said in my original post, the analog headphone output, also a Realtek device, likely using the same Realtek chip does work!
The other explanation is a hardware failure of both the main and mini sub hardware of the laptop just hours after installing FxSound after months of flawless use. I find that very unlikely, I was not listening to anything at very high volumes or anything, more just using FxSound to boost very faint content to normal volumes, so it’s not likely I overloaded anything.
I feel there’s a bug in FxSound and even wheb uninstalling FxSound there’s something left installed/in place that’s preventing the speaker output. All other audio devices I try work fine with or without FxSound installed including the Realek based analog headphone output.
