External Plugin Non-Interleaved

External Plugin Non-Interleaved

[Charles Eidsness]

I'm working on a small ALSA pcm/ctl plugin to add support for LADSPA modules 
that include real-time controls (unless I'm missing something it looks like the 
native ALSA LADSPA module doesn't include real-time adjustable controls). I want 
to use it as a system wide equalizer. I'm using snd_pcm_extplug, I want to force 
access to be non-interleaved only but I can't figure out how. Is there some way 
to force non-interleaved access for an extplug?

If you're interested you can find the first pass of my plugin here:

Thanks,
Charles

No, extplug itself cannot restrict the access format, so far.
It's possible to add a new restriction to extplug, though...

It would be a nice feature to have. I noticed that ioplug has that restriction, 
could
the restriction code some ioplug just be pulled into extplug?
