[Solved] mute automatically internal sound card

Hello
on debian 8.2/gnome 3 I have installed xfce (4.10) (and I'm really happy of that!!)
However, I have several problems to fix: the most important is a sound problem
I use a usb sound card (m-audio fast track mkII). But each time I boot, the internal soundcard is active (in pavucontrol, I have to "mute" it)
How can I desactivate it durably?
Furthermore, somtimes I use jackd (it doesn't always work and I have to restart it!) and when I close it, the control volum icon in panel doesn't work any more.
How can I fix all that? How could I at least understand how it works??

Re: [Solved] mute automatically internal sound card

Not really an Xfce issue, but the general process for disabling a device is to blacklist the kernel module.

cat /proc/asound/modules

...will list the sound modules. Identify the one you want blacklisted and create the file /etc/modprobe.d/sound.blacklist.conf with the content of:

blacklist SOUND_MODULE

...where SOUND_MODULE is the module name from the previous step. Then reboot.
