I can’t manage to get Allo BOSS work as master, it always works as slave. From DAC list I select Allo BOSS. In config.txt I see “dtoverlay=allo-boss-dac-pcm512x-audio”, but Allo BOSS works as slave. Are some additional changes needed?
Thanks.

pcm5122 does not generate BCLK and LR signals, but RPI does generate them. But it should be vice versa.
By means of logic analyzer I see that RPI does not try configuring pcm5122 as master (does not configure PLL, BCLK and LR as outputs and so on), instead RPI sets pcm5122’s PLL source to BCLK.
