Inno-maker DAC rpi3b + stutter

HI love the software, used other type before but didnt look as nice as this.

i have a couple of issues which may be solved with one fix. I have a Inno-maker DAC HAT running on my rpi3b+ but for the first seconds the sound plays perfect clear after that the song jutters with every second, I have buffer time set to %30 and internet speed is fine 100mbps+ my audio does also play too high of a pitch, using this hardware only spotify plugins.

please help.
