snapcast randomly creates new fifo queue and then can't read from it

[kunze-johannes]

Describe the bug
Hi.
First of all: Great software, I use it for almost 5 years now.
I do have a problem since almost a year which I can't seem to fix. Every once in a while (no pattern so far), the fifo queue under /tmp/snapfifo is being renamed (or deleted and recreated) as /tmp/snapfifo-01. Another fifo queue named /tmp/snapfifo-02 appears 5 min after.

My setting is not too exotic: I record incoming sound from bluealsa using arecord and then pipe it into the fifo queue. In other words: the raspberry that snapserver runs on and distributes sound to the snapclients, is also functioning as a bluetooth speaker I cast music to.

/usr/bin/arecord -D bluealsa -f dat --fatal-errors /tmp/snapfifo 2> /dev/null || sleep 10;
After renaming, snapaserver rightly complains about no /tmp/snapfifo queue being present.

I found nothing in your code that could explain the renaming.

Steps to Reproduce

1. Wish
2. I
3. Could :-(
