Ok. I think I solved. Thanks again for the suggestions! I just compiled the audio/ as is (adapting only my .mk files), and it goes just fine on my device: https://github.com/Renesas-EMEV2/Renesas-device_emev/commit/70ca2d4f00c58374982a78ea86a2997fe7b15200 I thought I had to change mixer control names, etc, but looks like that's not necessary...
