D: [pulseaudio] alsa-util.c: Trying upmixplug with SND_PCM_NO_AUTO_FORMAT ... this mean pulseaudio disable the format conversion of plug plugin from s16_le to float how about
aplay -v --disable-format -D upmixplug foo.wav
I: [pulseaudio] (alsa-lib)pcm_params.c: Slave PCM not usable
for error message you need to complie alsa-lib with
#if 1
#define RULES_DEBUG
#endif
in alsa-lib/src/pcm/pcm_params.c
seem err in sprepare
err = sprepare(pcm, &sparams);
if (err < 0) {
SNDERR("Slave PCM not usable");
return err;
}

Created attachment 99905 [details] my asoundrc including the rl-crossover (As requested in the faq, i mention this bug occured on Kubuntu, but it was reproduced by an user of #alsa on Debian) I've created a Linkwitz-Riley-crossover (4th order) in .asoundrc for upmixing 2.0->2.1 (see attached .asoundrc). The crossover works great with aplay or with vlc when selected as alsa output device. I can load any pcm from .asoundrc as alsa-sink, as long as there's no ladspa-filter in the signal chain. But when i do pactl load-module module-alsa-sink device=upmixplug, it fails with: I: [pulseaudio] client.c: Created 7 "Native client (UNIX socket client)" D: [pulseaudio] protocol-native.c: Protocol version: remote 28, local 28 I: [pulseaudio] protocol-native.c: Got credentials: uid=1000 gid=1000 success=1 D: [pulseaudio] protocol-native.c: SHM possible: yes D: [pulseaudio] protocol-native.c: Negotiated SHM: yes D: [pulseaudio] module-augment-properties.c: Looking for .desktop file for pactl D: [pulseaudio] alsa-util.c: Trying upmixplug with SND_PCM_NO_AUTO_FORMAT ...

D: [pulseaudio] module-udev-detect.c: /dev/snd/controlC0 is accessible: yes I: [pulseaudio] client.c: Freed 7 "pactl" I: [pulseaudio] protocol-native.c: Connection died. I get the same result with any other pcm from .asoundrc when a ladspa-filter is in the signal chain. Before trying to load a sink, i've always unloaded the soundcard (D2X) from PA to avoid any chance of a collision.
