1207611 - Windows 10/FireFox/Flash: Microphone does not work

Status: RESOLVED DUPLICATE of bug 1206278

(External Software Affecting Firefox Graveyard :: Flash (Adobe), defect)

Description

[Jeremy Noring]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36

Steps to reproduce:

I've filed this with Adobe as well; it is not clear to me where the bug lies, but flash microphone capture on FireFox running on Windows 10 appears to be completely borked.

To reproduce, on Windows 10, using FireFox with Flash 19 installed, go to any page that tests out microphone.  For example, http://webcammictest.com/check-microphone.html



Actual results:

Mic meter will be unresponsive (may be completely pegged, may be completely silent, but little/no movement) in flash despite working in system playback devices.  If it records anything, it'll generally be garbage.

Note that I can swap over to Edge/IE11/Chrome and have the page work immediately on the same machine.  I also tested Flash versions 17-19, no difference.  FireFox versions 39-41, no difference.  Strangely enough running the debug version of flash works.  


Expected results:

Mic meter should move normally,  audio should be recorded normally.  

We've had widespread customer complaints with our own application, so the issue is pervasive.

Is it specific to Win 10?

Comment 2

[Jeremy Noring]

Yes, as far as I can see, it is specific to Windows 10.  I am unable to reproduce this on Windows 8.1 or Windows 7.

Also, here's the defect on adobe's tracker as well: https://bugbase.adobe.com/index.cfm?event=bug&id=4061929 - I filed in both cases because it really isn't clear to me where the bug lies.

Jeromie, could you investigate if this bug is an issue with Adobe Flash + Win 10 or Firefox, as it has been reported in the Adobe's tracker too.

Oh yeah, this is a dupe of Mozilla 1206278.  It's non-trivial.  :)

Long story short, this is fallout from an architectural change in Windows 10.  Calls to the COM interface that we used to access Microphone data just fail in the context of Win10.  The assumption is that we're no longer allowed to call them from our integrity level.

We've talked to our engineering counterparts at Microsoft about it already and have a support case open with them to determine the best possible solution.  These types of issues tend to move slower than we'd like, but it's something that we definitely want fixed.

Any news?

Comment 8

[Jeremy Noring]

No news from Mozilla or Adobe; on the adobe defect, there's some indication that "protected mode" is causing this issue.

Comment 9

Bad to see this issue is not yet resolved and no updates... it's not safe disable protect mode so Microsoft and Adobe maybe is Adobe issue should fix.. awww hy are not exist an alternative to Flash? 
:S
