Hi Bob. I'd try adding the following 2 option lines to
your /etc/modprobe.conf.
options snd-via82xx index=0
options snd-usb-audio index=1
Tried and failed :)

But, thanks for the try. Sigh, this is getting to be quite frustrating!

I'm wondering if there is a problem with the usb or hotplug stuff? But
that seems to be a moving target as well.

For what it is worth, I also have a usb scanner and printer on the
system and they work just fine.


Surely there is a solution!

Hi Bob. Would you post the output of lsmod, so as to check the modules that are loaded, and to see if something is being loaded that shouldn't be.

Thanks. Both copies of the message came though just fine.

When someone answers you to this list, a message is both sent directly to
you and to the list, so you will get two messages (directly and from the
list)


Rebooted and have the following info. First, lsmod just after boot (with the USB Midi NOT working):

Well, in the first case two modules audio and snd_seq_midi are NOT loaded,
which are in the second case. This seems to be the main difference.
But I am sure you noticed that as well.

There is a bit of line wrapping going on, but that's obvious.

Anything leap out for you?
