Comment 1

[BugBot [:suhaib / :marco/ :calixte]]

The bug is linked to a topcrash signature, which matches the following criteria:

• Top 20 desktop browser crashes on release
• Top 10 content process crashes on release

:jimm, could you consider increasing the severity of this top-crash bug?

For more information, please visit BugBot documentation.

[Dianna Smith [:diannaS]]

:jimm any luck investigating here? Looks like the volume went up a little since first reported.

Comment 3

[Matthew Gregan [:kinetik]]

No major changes in AudioIPC between Firefox 129 and 130, but mio was updated from 0.8.8 to 1.0.1 in bug 1910523 (AudioIPC dependency change) and bug 1910513 (actual mio update) which landed in 130. That mio update includes this fix to the named pipe code, which is likely related to the crash spike. I'm not sure if that change caused the spike or revealed an existing bug in AudioIPC; I'll investigate further.
