Playback starts to stutter and audible beeping occurs when audio is paused

[mill1000]

This is an odd one and the 2nd time it's occurred.

Audio is streaming to a gmrender-resurrect instance when it begins to stutter with short breaks. When playback is paused at the I2S source, an audible beeping is heard. No overflows or other issues are reported in the console.

I used curl to grab a sample of the audio data and noticed that the download speed was approximately 130k instead of the usual 187k. Restarting the gmrender-resurrect returned the download speed to the expected 187k.

This is what the received audio data looked like. The gaps are approximately 500 ms long, with 140 ms burst.
