[NFB-Science] Screen Reader Audio Fix with graphiti

[John]

Hello,
> In Fall 2023 when I first started working with the Graphical Tactile Display (Graphiti) from Orbit Research I encountered a challenging problem. Another Graphiti user contacted me asking for a solution to this problem. My screen reader would speak audio great until I connected the HDMI and powered on the Graphiti. At this time, all audio would stop coming out of my computer. The initial remedy was to disconnect HDMI from Graphiti and reboot computer. In other words, I could have audio out of my screen reader or beautiful tactile images from Graphiti, but not both.
> 
> Since I have a refreshable braille display, I could work around the problem somewhat, but of course, what I was hoping for was both audio from screen reader and tactile from Graphiti.
> 
>  
> 
> I have had success getting the audio to come out of my laptop's internal speakers.
> 
> I believe they are referred to as RealTech Audio for my laptop.
> 
> I went to settings, hardware, sound and chose my desired audio output "RealTech Audio".
> 
>  
> 
> What was selected was "HDMI to USB".
> 
> This selection first began being the default after connecting Graphiti via HDMI to my laptop.
> 
> Moving the default to RealTech Audio makes the internal speakers speak the regular audio of the PC now.
