Hiss and crackle only at start of playback

Hi all
When I start a new album from Tidal through Volumio player I usually (but not always) get a 2 or 3 seconds of loud hiss which then goes away. Also at the beginning of each track, between 5 and 30 seconds in I get a short burst of crackling which again goes away.

I’ve increased the buffering which I thought worked for the crackling but has returned. It didn’t do anything for the hiss.

Also every now and again it will randomly skip to the next track.

This is all getting a bit frustrating.

Kit is Allo USBridge sig connected to Ethernet, into Topping D70 DAC.

Any help much appreciated. Cheers.
