Initial streaming works, resume / quit crashes (?) Sunshine

[falk4243]

I'm using Debian 11 with Mesa 21.2 from testing, which is necessary to make VAAPI encoding for the 5750G APU work and Kernel 5.16 (also from testing). Streaming (VAAPI or software) the desktop (xfce4) works, resuming or quitting after having disconnected once doesn't. The server log (turned up all the way) unfortunately shows nothing and stops as soon as trying to reconnect to an existing session; without Sunshine "officially" crashing. After receiving a timeout, the server is shown as offline by the client, though and needs to be restarted before another connection is possible.

I've tested this with the most recent Windows, Android and iOS Moonlight clients, always with the same result. Actually, the same setup (nearly, kernel version is newer) has worked a couple of months ago. Also, the network setup hasn't changed and I'm forwarding TCP 47984, 47989, 48010 | UDP 47998, 47999, 48000, 48002, 48010 as before. Opening up the host completely unfortunately doesn't make a difference, so it's very likely not a network problem anyway. Please let me know if you have an idea what might be causing this behavior. If you need more info, just let me know.

And "solved": One recent change I forgot about what having switched to Pipewire in the meantime. The kernel log showed a crash whenever disconnecting from a session. Switching back to Pulse, everything works as expected again.
