I much appreciated

Thanks!
I have put in /boot/efi/extraconfig.txt
dtoverlay=hifiberry-dacplus
dtparam=audio=on
dtdebug=1 <- this seems to be ignored. Where is the log file?
dtparam=i2s=on
and the fdt (examined using "dtc -I fs -O dts /proc/device-tree" -
thanks Matthias) gives very much the same as you have:
sound {
i2s-controller = <0x24>;
compatible = "hifiberry,hifiberry-dacplus";
status = "okay";
phandle = <0x79>;
};
...
pcm5122@4d {
AVDD-supply = <0x7c>;
CPVDD-supply = <0x7c>;
DVDD-supply = <0x7c>;
clocks = <0x7e>;
#sound-dai-cells = <0x00>;
compatible = "ti,pcm5122";
status = "okay";
reg = <0x4d>;
};
...
All looks OK but dmesg gives:
pcm512x 1-004d: Failed to reset device: -121
pcm512x: probe of 1-004d failed with error -121
Is this because I have a pcm5102 not a 5122? Or just that the address
(0x4d) is incorrect?
Any pointers gratefully received - and thanks for your patience!
