Re: soundcard confusion problem when re-starting NVDA

Tyler Spivey
 

Alright. So here's what's going on.

This is another one of those NVDA bugs that have been there for years without a fix.

What's going on is that when the synthesizer loads, NVDA gets the ID of the sound card. It uses that ID to speak through until you change it or until it restarts.
However, unplugging the sound card and plugging it back in might change its ID, and NVDA doesn't notice.


So to avoid this, just hit alt control n to restart NVDA and it should use the correct card again.

If it is expected, I'm wondering if there is a workaround?

This bit of info isn't connected to the problem but it does help in the explanation. When I listen through wifi headphones via the USB soundcard, I hear most audio through the headphones but system sounds still come from the laptop speakers. I've asked about this on this list before so understand what is going on with that and how I could change it if I was sufficiently bothered.

Anyway, what happened tonight was that I was trying to open a book I'd purchased in Adobe Digital Editions. ADE stopped responding and sometimes when programs stop responding (Firefox does this sometimes), closing NVDA and re-opening it allows NVDA to work with the program again.This did not happen this time and here's where the issue really starts.

I understand why NVDA switched back to using the laptop soundcard and speakers rather than the USB soundcard and headphones, but what was strange was that when I went and unplugged the USB soundcard (hoping to restore USB soundcard and headphone sound by unplugging the USB soundcard and plugging it back in again) when I unplugged the USB device I lost all sound. NVDA could only b e heard through the laptop speakers when the USB soundcard was plugged in but, when it was plugged in, no sound came through the headphones.

I'm curious about why unplugging the USB soundcard stopped all audio through the laptop speakers, whilst plugging it back in (which probably should have restored audio through the headphones) didn't restore headphone sound but did restore laptop speaker sound.

The only solution I could think of to get the different soundcards behaving the way they should, was to restart the laptop and unplug the USB soundcard before Windows rebooted. That is how I logged back in and have now re-connected the USB soundcard and am listening through my wifi headphones again.

My question is whether there is any way, other than restarting the laptop, to restart NVDA without causing problems between the soundcards?

I'm using NVDA 2019.2 and Windows 10 Version 1903 (OS Build 18362.476). My USB soundcard is quite an expensive one, an audioquest Dragonfly Red.

Grateful for any suggestions (other than the obvious one of not re-starting NVDA whilst an external soundcard is being used)

I ask because I'm on ISCA BBS, the only one I know of that's still going,
though there might be others. I have an addon that makes a client for it read
the text automatically as it comes in and let's you review it. It's nothing
fancy, I literally stole it from NVDA's internal code for PuTTY and changed
the window name, so it treats the client window as a terminal. I've been using
it for quite a while now. I've never bothered uploading it to the community
because I didn't think it would be useful to anybody but me, but since I just
made it work with 2019.3beta1, I figured I'd at least ask in case somebody's
been waiting for just such a thing to exist. If so, it does, and sorry I
didn't mention it sooner.


Alternatively, if you're on one of these and you've found a way to use NVDA
without an addon, I'd love to hear about it. You could run a client on a Unix
variant I guess, but this addon let's you do everything right from Windows.
You get a full editor and all, as opposed to single line editing with telnet.
If there's a way to do that on Windows without an addon, I'm really interested
in trying it out.

Moving Focus and Brows Mode Cursors at the same time in editable Browser Elements?

 

Hello,

I am wondering if there is a way to connect the focus mode to the brows mode in rich text editors or editable elements in the browser?

1.       Open:

https://www.tiny.cloud/docs/demo/basic-example/

2.       Press o to get to the "Application" and hit enter.

3.       Press escape until you are placed in the editing area.

4.       Arrow down several lines

5.       Press NVDA+space to go into brows mode.

6.       Arrow up and down to find out your cursor when editing is different than your cursor when in brows mode.

7.       In brows mode, hit h to go to "A simple table to play with" and hit enter.

8.       Press read current line and it will be on the last line you were on in focus mode.

 

I'm sure someone would find this behavior useful sometime, but it is really making using rich text fields annoying in the browser.

Is there some way to connect these two cursors together?

I have both Caret moves review cursor on, and Focus moves navigator object on.

Thank you,

Letter from a community add-ons reviewer: how you can help make NVDA add-ons compatible with NVDA 2019.3

 

Hi all,

 

Please circulate this letter to the wider community:

 

Dear NVDA users and the wider NVDA community,

 

I’m Joseph Lee, one of the NVDA code contributors and a community add-ons reviewer. On behalf of NVDA core and add-ons developers, I would like to thank you for your continued support for NVDA. And as the developer responsible for leading the much anticipated Python 3 transition research, I would like to personally thank you for continued encouragements, feedback, and guidance in making this transition work as smooth as possible.

 

One of the frequently asked questions for the past few months has been, “are my favorite add-ons compatible with future NVDA releases?” Until a few months ago, the answer was “not many”; today, a vast majority of add-ons are compatible with NVDA 2019.3, or will require this version to work. Since the release of NVDA 2019.3 beta on December 9, 2019, more add-ons are coming onboard the compatibility train, especially speech synthesizers such as Code Factory’s Vocalizer and Eloquence package, Vocalizer Direct and Expressive voices, and others.

 

As many of you may know, part of what makes NVDA great is a variety of community add-ons. Since late 2018, several community add-on authors were testing Python 3 version of NVDA internally to make sure their add-ons were ready in time for NVDA 2019.3. Since August 2019, add-on authors were encouraged to make their add-ons compatible, and a page listing compatible add-ons has been created to track the progress of this work, which can be found as an announcement in community add-ons website (addons.nvda-project.org).

 

As a community project, NVDA relies on community participation to shape its destiny. As part of this, you can make NVDA 2019.3 stable and even better by helping to make add-ons compatible on day 1 of NVDA 2019.3 era. As part of this effort, please take note of the following suggestions:

 

  1. Hold off on feature requests for a while: I know that many of you would like to see a cool thing or two included in add-ons. But as I noted above, NVDA 2019.3 is a huge release, with changes such as Python 3 that will affect many add-ons. So until NVDA 2019.3 stable version is released for everyone, please hold off on suggesting new features for add-ons so add-on authors can focus on making their add-ons compatible and stable.
  2. Provide feedback in a timely manner: although add-on authors will try their best to make sure their add-ons are ready for NVDA 2019.3, they cannot cover all bugs. If you do run into problems with add-ons that are specific to NVDA 2019.3 changes, please send feedback to add-on authors as soon as possible. On the compatible add-ons page, you’ll find not only compatibility information for add-ons, but also contact information such as email addresses of people who made add-ons possible.
  3. Encourage add-on authors: add-on authors are not superheroes – they are humans. Encourage them while giving feedback about their add-ons.

 

As a community, we are in this journey together – NVDA 2019.3 is all about preparing for the future and a necessary stepping stone to make sure you (users) can have equal access to technology. You can make NVDA 2019.3 better and truly revolutionary by participating in making sure add-ons are ready for the new year. My personal new year’s resolution for 2020 is to see 100 percent of community add-ons compatible with NVDA 2019.3 on the day it is released for everyone. I am certain that we as a community can make this dream a reality. Keep up the good work, and in the meantime, please test NVDA 2019.3 beta with add-ons and provide feedback to authors.

 

Thank you.

Sincerely,

Joseph

Re: Vocalizer expressive voices

Ok here is what I have found so far with the Vocalizer voices and the NVDA 2019.3 beta.
I am finding the voices very responsive and I think much better than the one core voices.
Having said that for some reason and I don't know if this was a NVDA beta issure or a Vocalizer issue. At a point after the voices working very well I had a need to reboot my system. I have american english voices installed and nothing else. For some reason NVDA started speaking in some other language. When I opened the NVDA UI the dialog box was also displaying something other than english. Had to totally remove NVDA and any left over NVDA folders to get back to speaking and showing english.

Re: NVDA saying new notification window

 

Yeah, sometimes a notification comes up and the window just stays up till you reboot.

My theory is its another sync issue it doesn't happen often but if you are in the wrong place it can happen a lot.

Just reboot and it will go away for a while.

Had you recently installed the 2019.3 beta by chance?  Installing a new version of NVDA often works smoothly, but occasionally random glitches like this pop up which are fixed with a reboot.

Re: NVDA sometimes loses control and needs to be restarted

Vaibhav Bhandari
 

Hi,
I too am having the same problem. Earlier I thought that it was due to
my down aero key having problems but found out that it is not so. It
happens less frequently with me if I use an external keyboard with my
laptop. I also have windows 10 version 1803 installed.
I have heard that this problem does not happen with NVDA 2017.4 and
the lower versions. Is it true?
Also, the last time this problem happened I fortunately was running my
NVDA on debug mode and have a log. I have attached it to the mail. Can
someone look into it?

Re: NVDA sometimes loses control and needs to be restarted

Yes, I've seen it happen with rapid typing in a few programs as well, I'm not sure the cause. I haven't been able to duplicate it recently, but I'll see if I can get a log the next time it happens. I suppose I should be smart and swap the alpha snapshots out for the beta release now the Python 3 stuff's in beta.

For emoticons, the addon helps to insert them without remembering
each simbol. As for emoji, if you use Windows 10, there is something
called the emoji panel. To access it, you use windows plus . period,
and pick the one you want to insert either by choosing a category, or
just by searching for an emoji. Your recently used simbols will
always be at the top.

It's not. Don't confuse Emoji and emoticon. An emoticon is composed
tipically of a combination of several punctuation marks, like less
than sign and number 3 for the heart emoticon. However, these days
emoji are used more frequently, which are unicode specific simbols
and modern apps often automatically convert emoticons to
alternative emoji. About the emoticons addon itself, it will be
ported as the Python 3 changes are already being tested by the
developer. Reading of emoji is supported by NVDA natively and does
not require additional addons.

It happens with me too, but it used to happen with System Access as well, so I just figured it was a screen reader thing. Restarting the screen reader has always fixed it. It was much, much worse with System Access, though, than it's ever been with NVDA, so I've never mentioned it. Since the last NVDA update (I'm using 2019.2.1), it hasn't occurred as often. It's usually when I'm doing things in Dropbox or occasionally when I'm using Tapinradio. sometimes it happens when I'm on a very what I call cluttered web site and things kind of slow down. I use firefox as my browser. As I say, though, it doesn't happen much now since the last NVDA update.

Hi everyone,

This has been happening for some time, on so many computers and with
so many different NVDA versions I can't believe I would be the only
one to see this, and it's not a huge inconvenience, but it's strange
and might be worth looking into. Regardless of the activity
sometimes NVDA "loses control". The key hooks (the NVDA key and all
the shortcuts associated with it) stop working. Using the numeric
keypad works as would without NVDA. Pressing Caplocks, which is a
NVDA key for me, triggers the CapLock function. NVDA still works
somewhat and tries to report information, but one can't open the NVDA
menu, read the time, look at the window title or indeed do lots of
things controlled directly by NVDA.

When does it happen? I've tried to reproduce the issue and it's
tricky. It never seems to happen at a given time or in any given
application. All I know is that it seems to "lose control" when a
lot of memory is required by other applications, which creates some
kind of lag. So this happens in a browser when the site has a lot of
scripts for instance. This can happen in Word if the document is
long. This can happen while the Windows CLI is opened and a
"demanding" task is running. This can happen when lots of update
information is sent to NVDA (the message queue gets long). It happens
more frequently if the machine on which NVDA runs doesn't have a lot
of memory. It sounds like a Windows lock, not NVDA's fault, but is
there a workaround? Restarting NVDA and the delay it causes isn't
really annoying, but it's definitely strange.

Most important question though: has anyone noticed this problem? Or
am I the only lucky one? Does happen!

Thanks,

Vincent

The key hooks (the NVDA key and all the shortcuts associated with it) stop working.  Using the numeric keypad works as would without NVDA.  Pressing Caplocks, which is a NVDA key for me, triggers the CapLock function.  NVDA still works somewhat and tries to report information, but one can't open the NVDA menu, read the time, look at the window title or indeed do lots of things controlled directly by NVDA.

When does it happen?  I've tried to reproduce the issue and it's tricky.  It never seems to happen at a given time or in any given application.  All I know is that it seems to "lose control" when a lot of memory is required by other applications, which creates some kind of lag.  So this happens in a browser when the site has a lot of scripts for instance.  This can happen in Word if the document is long.  This can happen while the Windows CLI is opened and a "demanding" task is running.  This can happen when lots of update information is sent to NVDA (the message queue gets long). It happens more frequently if the machine on which NVDA runs doesn't have a lot of memory.  It sounds like a Windows lock, not NVDA's fault, but is there a workaround?  Restarting NVDA and the delay it causes isn't really annoying, but it's definitely strange.

Most important question though: has anyone noticed this problem? Or am I the only lucky one?  Does happen!
