837937 - webrtc/getusermedia demo pages crash my whole desktop (not just firefox)

Status: RESOLVED INCOMPLETE

(Core :: WebRTC: Audio/Video, defect, P3)

Description

[mcdavis941 (sporadically reading bugmail)]

Using yesterdays nightly, visiting and exercising webrtc/getusermedia demo pages locks up my entire system after a few seconds.

It's happened separately on each of these:

- http://mozilla.github.com/webrtc-landing/gum_test.html
- http://mozilla.github.com/webrtc-landing/pc_test.html

STR:
1 - start nightly with a fresh profile
2 - go to http://mozilla.github.com/webrtc-landing/gum_test.html
3 - click audio
4 - click start
5 - wait a few seconds, ten or twenty
6 - mouse freezes and desktop becomes unresponsive

This was with the nightly from yesterday.  I'm currently running Mozilla/5.0 (Windows NT 6.0; WOW64; rv:21.0) Gecko/20130204 Firefox/21.0, so this was with whatever came before that.

(Maybe a configuration/driver problem on my end, so FWIW.)

I'm not getting a reproduction on my machine after running the audio test for 4 minutes.

I'm guessing it's driver level.

Can you give me information on what microphone you are using? The name of it? Version? Etc..

I don't have a microphone attached.  The system is a stock Dell XPS 430 desktop, unmodified except for upping the hard drive space.

So do you have an integrated microphone?

There's a microphone input jack on the back of the case, which I think goes to on-mobo integrated audio.  There's nothing plugged into that jack.  I'll have to double-check the details of what's inside the case.

Can you suggest another thing I could try, something other than Firefox, to try to see if I can make it fail without WebRTC?  I guess just try recording into some other program like VLC or Realplayer.

I checked, it's integrated audio, microphone jack on the front panel straight to connectors on the motherboard, line in on the back, again direct to the motherboard.

I tried recording with Windows' Sound Recorder, it seemed to work normally.  (Successfully recorded an empty sound file.)

If there's any other info you need, I'll be glad to provide.

[Randell Jesup [:jesup] (needinfo me)]

Information on the driver publisher, settings and version would help a lot.

Verifying that the capture rate supports 16000 would help.

Sorry Randell, I just saw your comment.  Looking at that now.

No.

Attachment: driver details

Here's some driver information.  I don't know exactly what you need, so feel free to let me know if this isn't it.
