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


Hello Brian:

I tried to replicate the problem here at home. Since I do not have a
projector, I used at TV instead. The computer is set to duplicate the
desktop on the second screen (i.e. the TV).

In this case, when I start the computer with the HDMI connector connected,
all sounds are played on the TV instead of the internal speakers, including
NVDA speech. However, when I start the slide show, NVDA goes silent as I
navigate through the slides, but Narrator happily plays it limited
information about each slide. I also added slide transition sounds to my
presentation and they play on the TV while NVDA remains silent. However,
once I restart NVDA, NVDA reads the slides as expected.

Therefore, I do not think this is a sound mapping issue.

Do all sounds go away, or just nvda. I was wondering if the sound was going
to hdmi.

I have 2 high-end Lenovo laptops with nVidia graphics cards. Both are
running Windows 10 Professional and Office 365 desktop apps. One
computer is 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
speech 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 or 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 show window until restarting NVDA after launching Power Point.
