Got it fixed by in with my MIO-892:

/etc/pulse/daemon.conf:
default-sample-rate = 48000

/etc/modprobe.d/azalia-microphone.conf
#Valid values for position_fix are:
#0 = Auto
#1 = None
#2 = POSBUF
#3 = FIFO size
options snd-hda-intel position_fix=0

For Echo/Noise Cancellation:
/etc/pulse/default.pa
load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echoCan$
set-default-source echoCancel_source
set-default-sink echoCancel_sink

Its mainly taken from the arch-wiki - but only 'this' combination worked for me.
