Hi Salvatore.

I think that the problem is with the codec, which is for a sound component on 
a modem. There are some problematic drivers that insist on grabbing card0, 
and as the actual soundcard uses card0, the soundcard is not able to be 

You could check this out on your FC 7 install. In a terminal type as below, 
and you should see a different codec listed, which is the actual one for the 
soundcard, and would be why sounds are working on FC7, and earlier. If that 
is so, we now need to stop the Motorola one grabbing card0.

grep ^Codec /proc/asound/card?/codec*

The easiest thing to try is to add a line to /etc/modprobe.conf, if it exists. 
If modprobe.conf doesn't exist on F10, create the file, and add a line like 
the example below.

options snd-usb-audio index=-2

You'll need to change "snd-usb-audio" for the driver that is for this modem. 
The -2 means that instead of the driver grabbing card0, it will use any other 
slot available, apart from card0, thereby allowing the actual soundcard to 
use card0.

Type /sbin/lsmod in a terminal, and see if you can see the module for this 
modem. It will probably have an "m" at the end of it's name. If you can 
identify it, exchange snd-usb-audio on the example line above with the one 
you think is correct. Next, pray, and then reboot, and see if the sounds work 
on F10.

Would you post me the full output from running /sbin/lsmod. It may help me if 
this problem shows up in the future on someone else's machine.

Also would you say if /etc/modprobe.conf exists on a fresh install of F10, or 
whether you have had to create the file.

All the best.
