Snapserver - lower pitch/clipping

For some reason my snapserver started playing the audio at a lower pitch and with increased clipping ...

I have snapserver on a Pi4 and snapclient on a Pi3

aplay -L returns:

null

Discard all samples (playback) or generate zero samples (capture)

Perhaps I need to edit pulseaudio.conf? When I SSH in, I'm not sure where pulseaudio.conf is located ...

Or do I need to clear some cache?

I had some unexpected power outage before the issue started .. someone flipped my mains a few times on the fusebox for the whole apt building ...

Any suggestions?

pactl list short sinks returns

1 Snapserver module-pipe-sink.c s16le 2ch 48000Hz SUSPENDED

2 librespot_sink module-null-sink.c s16le 2ch 44100Hz SUSPENDED

In this case I have Null Output but it looks like a sampling conflict is causing my change in pitch.

Shouldn't they both run at 48000Hz?

How do I force that to happen on startup?
