Crash in PulseAudio init on connecting #226
Description
Describe the Bug
I'm using Sunshine in the context of Games on Whales. It's been working great for a while using the older, pre-fork Sunshine, but recently I tried to run with version 0.14.0 and I get a segfault as soon as I try to connect with Moonlight. I grabbed this stacktrace with gdb:
Thread 23 "sunshine-dbg" received signal SIGSEGV, Segmentation fault.

Expected Behavior
No response
Additional Context
My server_info pointer is apparently non-null but still invalid, because this is the line that's crashing: https://github.com/SunshineStream/Sunshine/blob/70ae7a2fa9b33173eb949c86ec42a96e7b9e8c25/sunshine/platform/linux/audio.cpp#L400. I haven't done any further digging yet.
