I attempted to have one of my ethernet interfaces increased in priority
using an entry in the rtirq configuration file, but it did not seem to
work as seen below in the rtirq status. I expected eth2 to get set to
priority 70, but it is at the default of 50 along with all the other
non-sound interrupt handlers. Any help in understanding why would be
appreciated.

Also, is there any benefit to preventing the driver loading for the unused
audio section of my video card? The video card has an audio adapter that
only outputs over the hdmi port, which I am not using, but it gets set to
a high priority just like my ice card. Any concern with that, or just
ignore it?

Content of /etc/sysconfig/rtirq:

# IRQ thread service names
# (space separated list, from higher to lower priority).
RTIRQ_NAME_LIST="rtc snd usb i8042 eth2"

# Highest priority.
RTIRQ_PRIO_HIGH=90

# Priority decrease step.
RTIRQ_PRIO_DECR=5

# Whether to reset all IRQ threads to SCHED_OTHER.
RTIRQ_RESET_ALL=0

# On kernel configurations that support it,
# which services should be NOT threaded
# (space separated list).
RTIRQ_NON_THREADED="rtc snd"

# Process names which will be forced to the
# highest realtime priority range (99-91)
# (space separated list, from highest to lower priority).
# RTIRQ_HIGH_LIST="timer"
