Question

Systems with 4CH mic recording capability do not appear to work on Adobe Falsh enabled websites

For example Latitude 3189 on Rosetta Stone website. When starting a lesson, Adobe Flash pops up asking to select a Microphone. Correct mic is displayed. After selecting mic, the app will attempt to test the mic. Test fails because app cannot hear anything through the mic. Note that same audio driver works fine on Latitude 7480 with only 2CH mic recording capability. Recording tests work fine in Windows or at any non-Adobe flash site...Any ideas what may be happening here?

Hi,

I am Ken from Seattle Public Schools. We were the original submitters to Dell with this issue. I am adding myself to this in case there are additional posts. We did test the 3189 with Flash 30.0.0.113, and it works properly for Flash based recording applications for ActiveX and NPAPI. My understanding is that the rest of the fix needs to come directly from Google for PPAPI and will be submitting a support request for them as well.

Thank you,

Ken

Here’s the corresponding Chromium bug:

For browsers that support the ActiveX and NPAPI plug-in interfaces, the fix is in our current beta builds, here:

http://www.adobe.com/go/flashplayerbeta

That said, there is no way for us to ship a beta for ActiveX on Windows 10. Flash Player is a built-in component of Windows 10, and can only be installed via Windows Update. Microsoft does not make beta builds available for IE and Edge via Windows Update, so you won't have access to those until the release ships (which is currently slated for Microsoft Patch Tuesday) June 12.

Affected users *could* use Firefox and the NPAPI Flash Player beta.

For PPAPI browsers (Chrome, Chromium, Opera, etc.), the problem is happening upstream. We're continuing to investigate, but all indications are that it's not something that we have sufficient control over. My expectation is that we'll ultimately report that issue to the Chromium team for consideration.

We also believe that the content provider can enable Acoustic Echo Cancellation as a workaround. They should probably do this regardless, as it would improve the audio conferencing quality for all users communicating through chassis or external mic/speaker configurations.

Hi,

So for IE, Windows update should push the fix on 6/12?

And for Chrome, Content Provider = Realtek in this case?

Thanks,

Mark

No, Content Provider means the online service that the school district is using that requires Flash/Microphone support.

But yeah, barring some catastrophe that prevents us from shipping on-time, the current plan is that this would go out in the fix that we ship on June 12th.

To give you any useful advice, I'm going to need to know more about your computer and browser:

Latitude 3189

Windows 10 RS 3

Adobe Flash Version 28.0.0.161

happens on:

Internet Explorer 11

Google Chrome version 64.0.3282.186

Microsoft Edge

Realtek Audio driver version 6.0.1.8216

Note: Have tried multiple systems that only support 2ch mic recording and none of them have this issue. Its only systems like the Latitude 3189 that support 4ch mic recording that have this issue.

I doubt that we know what to do with two of those four channels. All of that audio code was written in the early 2000s. It may be that we're selecting the worst-possible choices (although you'd think that for compatibility, the driver guys would make the first two channels work for lowly stereo recording).

If you right-click on the Flash content and choose Settings > Microphone, do you see the right Microphone selected in the list?

If you do have the right device selected, do you see activity there?

If not, do you see activity in the Sound > Microphone tab in the control panel?

I can't find a good visual reference for the RealTek audio controls, but you may just have to poke around in the driver options to see if you can force it into stereo when you want to use Flash Player. I don't have a machine like this at my disposal, so I can't just go play with it and figure it out.

Also, if you haven't updated to the latest available RealTek drivers for that system (I didn't look to see if they were current) you might try that. A lot of times the OEMs like Dell will lag pretty far behind what's available from RealTek directly. You can always set a system restore point and then give the OEM drivers a shot. There were a lot of realtek audio problems when Win10 was first released, but those are pretty stable. This seems like it might be newer functionality though, and there might be a bugfix that's relevant.
