To reproduce.. Switch a stream to a remote tunnel, switch it back to a local sink.. Audio output stops for multiple seconds and then continues..
Below is what my local pulse server outputs when moving the stream back to a local sink..
I: resampler.c: Forcing resampler 'copy', because of fixed, identical sample rates.
I: resampler.c: Using resampler 'copy'
I: resampler.c: Using float32le as working format.
D: module-suspend-on-idle.c: Sink tunnel.spring.local.alsa_output.platform_snd_powermac_alsa_playback_0 becomes idle.
