Hi,

it's wise, even if somebody shouldn't experience this Intel onboard
device issue, to set up a proper /etc/modprobe.d/alsa-base.conf as
described by a previous mail, since even connecting an USB MIDI device
(not necessarily a MIDI interface, but e.g. a remote control KORKnano
or better) could cause a change of the order of audio cards randomly at
startup.

When using rtirq, it's wise to edit it's config. However, usually it's
possible to disable the integrated Intel onboard device, excepted of
the HDMI part and even if it shouldn't be possible, blacklisting or
removing drivers, instead of using the tools to optimise the Linux
install doesn't make sense at all.

                   The second config is from an Ubuntu install ^^
                   without giving USB top priority.
