Ok. So if I understand all of this correctly, the overall goal of the tones project is already redundant to your old proposal (or at least partially, Paul?).

Has there been any reason why it never made it into git HEAD?

So for this patch as-is, AFAICT Paul wanted the external lib as qualification task only and finally get things natively implemented during GSoC?

If so, we can first review this patch as RFC to give Ashutosh feedback to his coding & things. And wether or not he'll pass qualification, gets selected for a probably available slot etc, reads as if he's doing the GSoC project finally, we can have Ashutosh work on an implementation of the audio tones project. Assuming there haven't been any fundamental objections to Nicolas old proposal about such a thing already.

And then, it would of course only make sense to do this project based on what Nicolas old proposal was. Assuming it served the same goal.

Nicolas, can you please give a link here to your proposal for Ashutosh to find it easily?
