Not sure if that can be done, why would you want to?

It probably uses the snd-hda-intel kernel module, so just blacklisting that module would remove other HDA soundcards too.

find /sys/devices -name *01:00.1
/sys/devices/pci0000:00/0000:00:02.0/0000:01:00.1

sudo nano /etc/rc.local

thanks for reply!
I was able to solve this issue (see above) this could be a reason for a IRQ conflict which happens rarely ..
