@Mukul Kalsait I think it's Pixel 6a(GOS) issue (942,943,944), with Fiio Control it shows 48khz and there isn't any option to change, but on other devices it's 192khz (and Poweramp + ka1 works fine too). But I still don't know how it works perfectly fine with Fiio's own music app(and shows 192khz on fiio control inside music app) on 6a but not with other apps. Anyway thanks
