CallMeMike I seems that the Clock needs to be "resynced" some time, so the SOX Upsampling didn´t Change something as described before.

As you see, the Pops come and go, Always with the same Songs.... I used in this case SOX upscaling...

@Tim Curtis talks a lot of sense...

By the way, your last remark rings some bells... not sure about the meaning yet. You are saying that the issue happens with the same songs... is this a definate pattern?
Questions:
- Is it that switching during the playback of a playlist to a different song the issue gets triggered ONLY by the same songs (that you know of) and never by the others (that you know of)...?
- Do these 'same songs' belong to the same album?
- Can you verify by testing the playlist switch with all the songs in that album in order to define a clearer pattern?
- If there are more than one song from that album causing the 'noise' could you convert that album using an audio converter to the same sample rate target (so NO ESSENTIAL changes are done) and repeat the 'noise' test?

As I said some... some sneaking suspicion that has to do with your particular DAC board and the 'workaround' involving the standalone USB-to-I2S board which provides 'noiseless' playback.
