I am trying to build and install freeswitch on Raspberry PI computer in order to use skype and asterisk.
When I run this command - insmod ./skypopen.ko
I get this error- Error: could not insert module ./skypopen.ko: Device or resource busy
I ran 'lsmod|grep snd' earlier and it showed some modules. I used rmmod to remove them. Now 'lsmod' does not show any modules. I still get the device busy error when I run insmod.
How can I fix this error?
