Re: About DSP API

If I put the DSP in play mode (B_PLAY_UL) I can send some garbage on dsp_api.ndb->a_du_1 and the peer will play it, but if I peek the data at dsp_api.ndb->a_du_0, it's null filled.  If I revert the play mode, I can see data on dsp_api.ndb->a_du_0.

I guess the play ul both enables the tx from a_du_1 and also disables the audio compression stuff ... You can try to modify the content of a_du_0 at the time of the interrupt without leaving but I'm not sure it'll work or if the dsp will already have taken the data ...

Cheers,
