Try these entries:
defaults {
ctl.card PCH
pcm.card PCH
pcm.device 7
}

Usually, you should configure the receiver to expand audio data to 5.1
channels. If you really want to force the PC to do this, ensure that
you have the alsa-plugins package installed, and try this instead:
pcm.!default {
type plug
slave.pcm {
type upmix
slave.pcm {
type hw
card PCH
device 7
}
channels 6
}
}
