Hi Daniel
Do you mean CPU-dummy + dummy-Codec ? But anyway, simple-card/audio-graph DPCM support is very limited. Unfortunately it doesn't have flexibility...
Yes, exactly. I need 1 DAI link with 1 FE + 1 BE for DSP / SOF usecase.
simple-card support it if it needs convert-rate or convert-channels. Please check below
static simple_for_each_link(xxx) { ... for_each_child_of_node(node, np) { /* * It is DPCM * if it has many CPUs, * or has convert-xxx property */ (1) if (dpcm_selectable && (2) (num > 2 || (3) adata.convert_rate || adata.convert_channels)) ret = func_dpcm(priv, np, codec, li, is_top); ...
(1) : using simple-scu-audio-card (2) : 2 nodes or more (3) : has convert-xxx property
Thank you for your help !! Best regards --- Kuninori Morimoto
