Hi Stephen, Mark

Thank you for your checking

OK, I checked Tegra sounds, and it is using same device pointer for platform and cpu.
My FSI is same style.
But I wonder is this normal style ? >> Mark
If it is very normal style, I can remove "platform" from simple-audio.

Thank you

I see.
I will remove name-base matching from simple-audio
