I don´t think the patch is already included in the dietPi v144 release. I experienced the same pop noises at the beginning of a new DSD album or when using the track skip function on my McIntosh C2600 preamp with attached Raspi via USB. This happened in native DSD and also in DSD over PCM mode.
After applying the patch to the v144 release the pop noises have gone in both DSD modes.
