DSD Upsampling - "pop" sound then stops playing

Windows 10
Audirvana 1.2.2 (1038)

While streaming a lower bit rate album (16-44.1) via UpNp to my streamer and choosing Upsampling to DSD64 playback stops after 2 or 3 songs (variable). At the end of the song I get a popping sound and no more playback. If I set Upsampling to power of 2, etc., no problems. It’s only when To DSD is selected for Upsampling.

Streamer and (if separate) DAC?

Hi everybody!
When first time used the Ifi nano DSD with upscaling to max DSD 256, there occured POP sounds. Need to restage the situation, I’ll be back :sunglasses:

I’ve had the same intermittently with microRendu and iFi micro-iDSD.
