Plug fails to convert float mono to float stereo,
which is required when plug is used for float-only slaves
like "jack" or "ladspa".
Steps to reproduce:
#~/.asoundrc
pcm.!default {
type plug
slave.pcm { type null }
slave.channels 2
slave.format FLOAT_LE
}
# aplay -f FLOAT_LE /dev/zero
A possible workaround is to use two plugs:
pcm.!default {
type plug
slave.pcm {
type plug
slave.pcm { type null }
slave.channels 2
slave.format FLOAT_LE
}
slave.format S32_LE
}
But shouldn't "plug" do that automatically?
PS: the workaround makes `aplay -fFLOAT_LE /dev/zero` freeze on Ctrl+C,
but that's a different alsa 1.0.27 regression that I have not tracked yet.
