alsa-project/alsa-plugins issue #25 was opened from krumpfwylg: Hi, I've noticed the [latest commits](https://github.com/alsa-project/alsa-plugins/pull/2) 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 ?
