Hi,

MSI z87-GD65 GAMING motherboard's ALC1150 plays SND_PCM_FORMAT_FLOAT with noise[1] other non float formats work well. As soon as I changed /etc/asound.conf from

pcm.!default{ type hw card 1 }

to

pcm.dmixed { type asym playback.pcm { type dmix ipc_key 5678293 ipc_perm 0660 ipc_gid audio

slave { channels 2 # make 6 or 5.1 channel pcm { format S16_LE # S32_LE rate 48000 # can also be 44100 type hw card 1 # your card device 0 # your device subdevice 0 #important? }

period_size 1024 buffer_size 8192 }

bindings { 0 0 1 1 # Uncomment below if using 6 channel # 2 2 # 3 3 # 4 4 # 5 5 } } capture.pcm "hw:0" }

pcm.!default { type plug slave.pcm "dmixed" }

SND_PCM_FORMAT_FLOAT plays without a problem.
