【GNURadio】RTL_test error 的解决方案

使用GNURadio听FM广播的时候,遇到错误信息:

...
In the first case, please either detach or blacklist the kernel module (dvb_usb_rtl28xxu)
...

遇到这个情况,Google到一个永久的解决方案:

If this works, and you don't want to use the device for TV reception,
you can stop the module from ever being loaded, solving the problem
permanently.  The exact method depends on your Linux distribution, but
for me (running Arch Linux) I create a file in /etc/modprobe.d with
a .conf extension (I called it "no-rtl.conf") with these contents:

  blacklist dvb_usb_rtl28xxu
  blacklist rtl2832
  blacklist rtl2830

基本的做法就是

sudo vim /etc/modprobe.d/no-rtl.conf

在文件中写入:

  blacklist dvb_usb_rtl28xxu
  blacklist rtl2832
  blacklist rtl2830
