Before filing a bug for this, I want to gather some opinions
from other people's experience.
I think the strange problem started occurring after the Windows
10 May 2020 update. The "Microsoft Sound Mapper" does not show
correctly in the list of audio output devices in NVDA's dialog
for selecting a synthesizer. The device can be selected and
used, but instead of a name for it, there is only a blank item
in the list. On my machine Windows 10 is in bulgarian with all
locale settings set to "bulgarian". But I just for the test
changed the Windows display language to english and the problem
remained. I haven't changed the other locale settings (e.g. the
settings for time, date, currency and other similar things
format) during that testing. Should I? Could the locale settings
affect how that device's name is displayed?
I can reproduce this on at least 3 machines. All of them are
running Windows 10 May 2020 update. On 2 of them I'm running the
latest alpha snapshot of NVDA. On the 3rd one - NVDA 2020.1. All
of the machines have their locale settings set to "bulgarian".
I'm not for now filing a bug against NVDA due to one more
reason - I can reproduce similar (if not the same) behavior with
Audacity. If I open Audacity and press Shift+O to invoke the
dialog for choosing an audio output device, the "Microsoft Sound
Mapper" one, which is also selectible in Audacity, is displayed
only as " - output" and I think it should be displayed as
"Microsoft Sound Mapper - output".
Can someone else reproduce this in NVDA and/or Audacity? If so
and it is not an NVDA issue, how to report this to Microsoft, so
they can easily reproduce it? Because it is not like the
"Microsoft Sound Mapper" is easy to encounter and check out in
Thanks much in advance!
