Obviously your system is set up to run a script when your modules is downloaded, and the program alsactl is problematic. Did you install those new libraries etc. If so you seem to have a problem. You could just do rmmod snd_azx instead of using modprobe. If you look in /etc/modprobe.conf or one of the files in /etc/modprobe.d/ you will presumably see that the snd_azx module has a command to run alsactl befor unloading the module. > > Am I missing something here?
