[Tracking Requested - why for this release]:
There is a startup crash in avmsnd.dll (AVM TSP Sound Driver) on Windows 10 that seems to be spiking in Aurora 49.0a2 builds starting on 2016-08-03. I'm not sure if this is related to Flash but this is crashing in the plugin process and Flash shows up in most reports.

Comment 1

[Sylvestre Ledru [:Sylvestre]]

Quite a low volume but it might spike in release.
Anthony, Milan, not sure who could help with it? Thanks

Comment 2

[u279076]

I'm not sure what is driving the spike but it seems to be isolated to August 3. You can see the graph for yourself by going to http://ashughes1.github.io/metrics-graphics-gfx/, entering avmsnd.dll@0x3918 in the Crash Signature Lookup field and clicking "graph". You'll see that August 3rd saw a very big spike on a single day. I'm inclined to think this is an isolated incident that may be out of our control.

However, I need someone else to look at this to confirm.

[Milan Sreckovic [:milan] (needinfo for best results)]

This is a sound DLL, so we could start there.  If that gets us nowhere, this crash (https://crash-stats.mozilla.com/report/index/c1d77acc-818e-4b9a-b940-787e52160805) suggests sandbox involvement.

[Anthony Jones (:ajones, :kentuckyfriedtakahe, :k17e)]

The number of installations is very small.

Looks like a Flash crash, so I'm redirecting to Benjamin.

Comment 5

[Benjamin Smedberg]

These are all plugin-process crashes. I can't tell whether this is a real driver or malware. If it's malware, I'm happy to DLL-block, but otherwise I don't think it's worth effort to dive into this.

Comment 6

[Marco Castelluccio [:marco]]

The crashes on 48 and 49 seem generated by a small number of users, for example on 48.0b10 there are 36 crashes from 1 installation.

Comment 7

[Marco Castelluccio [:marco]]

We've had another spike on August 8th, but still all crashes are generated by a small number of users (e.g. 33 crashes from 3 installations on 49 Beta). All the reports have the same version of the avmsnd.dll library (2.4.0.0).
