Jack and ARM

Hi,

I use Jack with an ARM 9 target.

It does not work because my CPU does not have a FPU -> alsa-lib configuration detect that my target is soft float then it desactivates FLOAT_LE support.

If I force FLOAT_LE support in alsa lib, It could works but It’s clearly not CPU efficient.

Does it any way to use an integer type as interface format with jack ?

Thank you.

Fabien

No, there isn't. All programs that use Jack expect to deal with floats
only. There is no scope for format negotiation.
