This looks like one of (many[1][2][3][4]) bugs in OpenAL's PulseAudio
backend (apparently OpenAL's upstream maintainer doesn't use PulseAudio,
which I don't either).  I found reports of it affecting at least one
other game.  If we can't solve it here, I'll reassign.

An apparent solution is to edit "/etc/openal/alsoft.conf" and under
"[pulse]" change "allow-moves" to "true".  Can you try this and report
whether that solves the issue?

It's also possible that there's an infinite loop somewhere in 7kaa's
src/openal/openal_audio.cpp triggered by this OpenAL error.  Could you
please install 7kaa-dbgsym, run 7kaa under gdb, reproduce the hang, and
get a backtrace?

$ apt install 7kaa-dbgsym gdb
$ gdb 7kaa
(gdb) run
^C
(gdb) backtrace
(gdb) quit

Bug#1034649: 7kaa: Unplugging USB headset hangs 7kaa

[Nils Dagsson Moskopp]

Package: 7kaa
Version: 2.15.4p1+dfsg-1
Severity: normal
X-Debbugs-Cc: nils+debian-p...@dieweltistgarnichtso.net

Dear Maintainer,

whenever I unplug the USB headset while 7kaa is running, it hangs.
7kaa prints a single line of output to the terminal, quoted below:

> AL lib: (EE) ALCpulsePlayback_streamStateCallback: Received stream failure!

“lsusb” outputs the following information about the USB headset:
