Question about upmix plugin

[krumpfwylg]

Hi, I've noticed the latest commits done to the upmix plugin, but there's something I don't understand.
Line 24 of pcm_upmix.c is #define UPMIX_PCM_FORMAT SND_PCM_FORMAT_S16
Does that mean the upmix plugin is still only capable of using S16_LE format ?
Or does the UPMIX_PCM_FORMAT value can get changed to S32_LE by tweaking it in asoundrc file ?

Yes. But you can change source.

No.

In the future, would that be possible for the upmix plugin to get the format information S16/S32/other (with a default set to S16) from the asoundrc file, allowing the user to change format in a more friendly way than having to patch & recompile ?
Thanks for answers :)
