ok, i think it must be starting before alsa, cos here's the situation:

1. just to clear up - my sound card has now made it's home on irq #5 -
this has held true after numerous reboots, checked with

cat /proc/interrupts:

           CPU0

2. after booting, the output of

/etc/rc.d/init.d/rtirq status


is:


  PID CLS RTPRIO  NI PRI %CPU STAT COMMAND
  276 FF      80  -5 120  0.0 SW<  IRQ 8
  878 FF      60  -5 100  0.0 SW<  IRQ 3
  954 FF      60  -5 100  0.0 SW<  IRQ 4
  929 FF      59  -5  99  0.1 SW<  IRQ 11
  374 FF      50  -5  90  0.0 SW<  IRQ 1
   20 FF      49  -5  89  0.0 SW<  IRQ 9
  297 FF      49  -5  89  0.0 SW<  IRQ 12
  333 FF      46  -5  86  0.1 SW<  IRQ 14
  335 FF      45  -5  85  0.0 SW<  IRQ 15
 1886 FF      40  -5  80  0.0 SW<  IRQ 7
 2054 FF      39  -5  79  0.0 SW<  IRQ 6
 3462 FF      38  -5  78  0.1 SW<  IRQ 10
 3695 FF      37  -5  77  0.0 SW<  IRQ 5


3. however, after running:

/etc/rc.d/init.d/rtirq restart


the ouput is:


  PID CLS RTPRIO  NI PRI %CPU STAT COMMAND
  276 FF      80  -5 120  0.0 SW<  IRQ 8
 3695 FF      70  -5 110  0.0 SW<  IRQ 5
  878 FF      60  -5 100  0.0 SW<  IRQ 3
  954 FF      60  -5 100  0.0 SW<  IRQ 4
  929 FF      59  -5  99  0.1 SW<  IRQ 11
  374 FF      50  -5  90  0.0 SW<  IRQ 1
   20 FF      49  -5  89  0.0 SW<  IRQ 9
  297 FF      49  -5  89  0.0 SW<  IRQ 12
  333 FF      46  -5  86  0.0 SW<  IRQ 14
  335 FF      45  -5  85  0.0 SW<  IRQ 15
 1886 FF      40  -5  80  0.0 SW<  IRQ 7
 2054 FF      39  -5  79  0.0 SW<  IRQ 6
 3462 FF      38  -5  78  0.1 SW<  IRQ 10

which looks to be the way it should happen ...

/etc/rc.d/rc5.d/S88rtirq
/etc/rc.d/rc6.d/K19rtirq


5. and just for good measure, here's the output of

cat /proc/asound/cards:

0 [Live           ]: EMU10K1 - Sound Blaster Live!
                     Sound Blaster Live! (rev.7, serial:0x80611102) at
0xd000, irq 5


hope this helps!

ps - if rtirq is going to be giving my soundcard a priority of 70, does
that mean i should indicate a priority of 69 in qjactctl?
