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

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...
Thanks
Richard
