Hi Pierre-Louis

Hmm... this is strange...
New snd_soc_compensate_connection_map() will add default ch_maps for all
dai_link...
Oh, is it using topology or something which doesn't call
snd_soc_bind_card() ? If so could you please try to call
snd_soc_compensate_connection_map() ?
(I guess it is using soc_tplg_fe_link_create() ?)
If it could solve your issue, v5 will handle it.
Thank you for your help !!
Best regards
