In alsamixer, there is a switch to select between stereo and mono diffential output for the LINE output (that has no notable effect), but not for the Headphone output. Driver limitation/bug? Hardware deficiency? Configuration error? Any other idea? FWIW, this is the DT overlay to get any sound at all: /dts-v1/; /plugin/; / { fragment@0 { target = <&codec>; __overlay__ { status = "okay"; allwinner,audio-routing = "Headphone", "HP"; }; }; }; Regards, Michael _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
