Hi Steen,
Glad to have you back working on Picoreplayer again.
I’ve done the test with V1.06 and added dwc_otg.fiq_split_enable=0 in
/boot/cmdline.txt

DAC:
Hifimediy Sabre DAC (old model with TE7022L chip, does not support
88Khz)
Command line:
-o plughw:CARD=DAC,DEV=0 -n piCorePlayer
And I tried the option -a 16::24_3:1 -r 96000 as suggested by al3ph in
the topic message #374.  

Results:
16&24b 44K: still  static pulses/crackles while playing back
24b 48K, 88K & 96K: no issues

I also tried also the sueezelite upsample option and added -u X. However
no better results.

I would suggest you buy the new Hifymediy Sabre U2  DAC for testing
purposes.
The U2 uses the SA9023 USB receiver chip from SAVITECH (not to be
confused with the DAC chip ES9023). It accepts 32Khz, 44.1Khz, 48Khz,
88.2Khz and 96Khz inputs at 16 and 24bit. 
Including postage from China to Denmark I think you can get it for the
US$ 80
Maybe you can send a PM to soundcheck and ask him for an advise. He is
the one who invented the TOUCH TOOLBOX 3.0 for the SBT.

Gr. Willem
