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
