Just use the hifiberry-dac DT overlay contents, look for the hifiberry-dac- overlay.dts

Thanks Both Looking at hifiberry-dac-overlay.dts, it specifies i2s-controller interface and pcm5102a-codec I have added i2s to extraconfig.txt with "dtparam=i2s=on" There is no line starting "dtparam=audio=" in either config.txt or extraconfig.txt, so tried with (and without) "dtparam=audio=off" I now have in /boot/efi/extraconfig.txt: dtparam=audio=off dtparam=i2s=on dtoverlay=hifiberry-dac None of these lead to anything visible in dmesg or /proc/sound (other than vc4-hdmi-hifi-0 device) Should I have a module named "pcm5102a" or similar? I see there is a file "pcm5102a.c" under sound/soc/codecs/ in the kernel source, and it seems to be 'live' in both Kconfig and makefile, but no module with 5102 in the name. As far as I can see, TI SOC support is enabled in "make menuconfig". As always, I am grateful for any more suggestions please...
