e100 is a network driver not a sound driver, are you sure you aren't
disconnecting the Ethernet interface you are logged in over or
something? You probably want /sys/bus/pci/drivers/snd_ens1371/unbind, I
would actually follow the symlink
at /sys/bus/pci/devices/0000:00:0b.0/driver instead of going
vi /sys/bus/pci/drivers to be sure of getting the right device.

Below is the script I use to attach a device to pciback, it takes a list
of pci devices as its parameter.

#!/bin/sh

if [ $# -eq 0 ] ; then
   echo "Require a PCI device as parameter"
   exit 1
fi

for pcidev in $@ ; do
    if [ -h /sys/bus/pci/devices/"$pcidev"/driver ] ; then

        echo "Unbinding $pcidev from" $(basename $(readlink 
/sys/bus/pci/devices/"$pcidev"/driver))
        echo -n "$pcidev" > /sys/bus/pci/devices/"$pcidev"/driver/unbind
    fi
    echo "Binding $pcidev to pciback"
    echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/new_slot
    echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/bind
done
