Disable Rockchip Soundcard

[Hiabst]

Hi, i want to disable the "rockchipminiarm" sound card:

root@innotune:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Audio [USB Audio], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Audio [USB Audio], device 1: USB Audio [USB Audio #1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Audio [USB Audio], device 2: USB Audio [USB Audio #2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: rockchipminiarm [rockchip,miniarm-codec], device 0: ff890000.i2s-i2s-hifi i2s-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I wanted to add the module of the soundcard into /etc/modprobe.d/blacklist but i can't find out wich module the soundcard uses.

Thanks in advance!
