Re: No voice, Power Point Slide Show view on Laptop with HDMI connected, NVDA restart fixes problem

Have you tried
Use f5 to start the slideshow
Use ESCAPE to close the slideshow
Use F5 again to start the slideshow

I find that starting the slideshow a second time works more
consistently than the first try.

Hello Joseph:

I will look into this as I try to replicate the problem using a TV monitor
instead of a projector and see if the sound actually gets rerouted.
this only happens on the Power Point Slide Show window. All other windows
continue speaking out the default speaker. I would think that all speech
would be rerouted and not just the slide show. Additionally, once I restart
NVDA, I can open and close Power Point and the speech continues to come out
the default speaker when starting a slide show.

Also, Narrator does not exhibit this problem.

This may have to do with audio output redirection: when an HDMI cable is
connected, sound is sent through the cable, so NVDA may not recognize that
you've still got your internal sound card active. You can ask NVDA to speak
through a chosen sound card via Synthesizer/output device combo box

Subject: [nvda] No voice, Power Point Slide Show view on Laptop with HDMI
connected, NVDA restart fixes problem

I have 2 high-end Lenovo laptops with nVidia graphics cards. Both are
running Windows 10 Professional and Office 365 desktop apps. One computer
brand new while the other is 3 years old. These are work computers, so
Windows and Office are updated within the last few months and not
necessarily running the absolute latest updates. I am running the latest
released version of NVDA and have no addin present. I have Microsoft Speech
API Version 5 as my voice.

If connected to projectors using the HDMI port, putting a Power Point
presentation into slide show mode (by pressing the F5 key) I lose all
output on that particular window. It doesn't matter if I am using the
internal speakers or am connected to a wired or wireless headset. Alt
tabbing to other windows and NVDA speaks just fine, but not on the slide
show window. Moving from slide to slide produces no speech. If the HDMI
connection is not present, NVDA speaks just fine in slide show mode.

If I now restart NVDA with Power Point still displaying the slide show and
the HDMI connection still present, everything works as expected. NVDA reads
the slides as I navigate from slide to slide, using the internal speakers
connected headset.

I tried restarting NVDA after booting the computer to see if it was a
problem with the autostart of NVDA completing prior to other parts of the
system completing initialization, but it still failed to speak in slide
window until restarting NVDA after launching Power Point.
