NBFM decoder doesn't work since v0.5.0-beta1 #1430

OS: Linux Mint 21.1 (x86-64) CPU: Intel Core i7-6700K Tuner: RTL-SDR

NBFM decoding has never worked for me since I started using SDRTrunk in mid 2022. No audio regardless of squelch setting and no power indicated in the Channel tab. I don't know why it works for most users but not me. In Discord, 11a1 said they had the same issue on multiple OS's, but don't remember how they resolved it. Edit: 11a1 clarified that it worked most of the time but it was possible to get it into a state where it doesn't work at all, which sounds like a different issue unless I'm somehow constantly getting it in that state before it has a chance to work.

Regression testing found that the issue began with v0.5.0-beta1, specifically commit 0eec2e7. That is a beefy commit with a lot of changes related to the NBFM decoder, making it difficult to find the root cause. On a related note, that same commit introduced the need for PR #1182 for me to get it to build.

Fixed in v0.6.0-alpha6 [#1562]. Thanks!
