I was finally able to get the machine on-line and used the RPM repository.

I will need bear that in mind -- altho' there's some weirdness in all of 
this 'cos at one point I removed the on-board sound in kudzu. . . .

"alsamixer -c 1" results in

    alsamixer: function snd_ctl_open failed for hw:1: No such file or directory


"alsamixer -c 0", however, did launch alsamixer, presumably 'cos I 
removed the on-board sound in kudzu. . . .

Actually, just the envy24control -- I'm assuming (again) 'cos I removed 
the on-board card thro' kudzu.  I wonder if perhaps that isn't part of 
the problem . . . .

Anyway:

    0 [M1010LT          ]: ICE1712 - M Audio Delta 1010LT
                          M Audio Delta 1010LT at 0xc800, irq 5

Yes, altho' I'm not quite sure of how to use it; it's a bit different 
from the comparable control panel in Windows.  I'm assuming that DAC 0 . 
. . 7 refers to analogue outputs and ADC 0 . . . 7 refers to analogue 
inputs, but I have no idea what IPGA [0 . . . 7] means, nor its relation 
to ADC.

Unfortunately, I still don't have sound.  If I open Audio Player and try 
to play a CD, I get an alert:

    Please check that:

    Your soundcard is configured properly
    You have the correct plugin sleected
    No other program is blocking the soundcard


The selected output plug-in is ALSA 1.2.10 out plugin {libALSA.so].  
When I go to configure it, it's set at the default PCM device, but even 
if I change it to M Audio Delta 1010LT: ICE1712 multi (hw:0, 0), I still 
get the same alert.

Needless to say, it's immensely frustrating to come this far and not be 
able to do anything 'cos I have no sound. . . .
