Subject: ASoC: No stereo on Banana Pi M2 headphone jack
Date: Wed, 30 Dec 2020 23:58:13 +0100 [thread overview]
Message-ID: <20201230225813.GA6402@a98shuttle.de> (raw)
Hi all,
I'm in need for stereo sound on the headphone jack of a Banana Pi M2
(Allwinner A31s), but I'm getting only mono differential (I assume at
least, because I can hear both channels in either speaker).
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
