back with my GraveAudio DA06 (CX31993), set it to avoid resampling, locked to 24-bit
/etc/pulse/daemon.conf
...avoid-resampling = true
alternate-sample-rate = 192000
resample-method = soxr-vhq
default-sample-format = s24
pretty okay now I guess the initial hiss/crack problems were due to it being relatively new/unused like a classic unprimed capacitor
it is now reminiscent of my 0.1> ohm alc1220 workstation dac but even more nostalgic is the mad amounts of stereo crosstalk I get when using a TRRS earphone which makes it sound like traditional "not so great crosstalk but linear phase" devices but devoid of any hiss (those who have them probably probably have cabling issues).
with a TRS connector it has less crosstalk (only appears above 60% volume) - with a TRRS connector it would have crosstalk at about 20% volume, maybe the way the dac is wired with the microphone is crosstalk problem (at the same time a alc5686 usbdac have no crosstalk issue on any device I own). also I think the fullness/response of bass of DA06 is legitimately definitely 1> ohms impedance output https://reference-audio-analyzer.pro/report/amp/graveaudio-da06.php which is an absolute upgrade to anyone wanting a budget sub-0.5 ohms dac and 32-16ohm iem crowd.
though the only problem I get now is microphone detection is not as smooth but I don't use it that much and seems like a linux driver problem.
earphone buttons/controls do work perfectly for TRRS with DA06. got the blue version so the copper CX-Pro might perform differently.
