Re: [alsa-devel] Complex hw buffer with MMAP_COMPLEX?

That is, we're dealing with 25 (or 26 for output) interleaved streams with two or eight channels each.

How could we represent such a layout in ALSA, that is, how are we talking to userspace? Would one create subdevices and rejoin them via plughw?

Is it possible to start/stop the streams independently? If yes, this might be useful.

(And subdevices are usually used for streams that are mixed together.)

Or use MMAP_COMPLEX and then let every application deal with it on its own?

Alsa-lib can automatically convert this. Applications that insist on using hw devices have to deal with it (Jack does).
