Yes, I have one of those cards, too. Nice. Good quality audio. It is ice1712
based and envy24control works fine.
Hmm, I had a look for the command line options for envy24control in the man
page. Couldn't find anything to adjust number of input channels displayed.
That's with the alsa-tools-0.9.0rc6-53 that comes with SuSE 8.2. Maybe a
later one adds them? My envy24control shows all 10 PCM input channels of the
internal ice1712, even though the Audiophile-2496 only has 2 analog and SPDIF
digital (2 channels) inputs from the outside world. I haven't explored all
permutations and combinations of the panels.
0.9.0rc6 is pretty old. The news items listed at
alsa-project.org put
that somewhere between these 2 dates:
2003-01-28 0.9.0 release candidate #7 (alsa-driver, alsa-lib,
alsa-utils and alsa-tools packages) is available for download.
2002-10-25 The fix for GCC 3.2 has been integrated into the 0.9.0rc5
package. Please, redownload the updated package from our server when you
reached this problem. (New package is dated 2002/10/25)
is there anything mentioned if you do:
envy24control --help
Most of the time I'm only working with 2 channels of my Delta66 so I
start it something like this (may not be exact, I'm not at home so I
can't check):
envy24control -i2 -o2 -p2 -s0 &
For 2 in, 2 out, 2pcm and 0 spidif.
Elsewhere, I've grumbled about the "lack of
integration" between apps like
audacity and xmms volume slider and the envy24control. The volume sliders on
the apps are "dead". You MUST control the volume on the envy24control. Dunno
if that's a permanent condition? ...likely to get fixed? how?
Not sure what to say about that ... I haven't used audacity and I never
cared for xmms. I use alsaplayer when I just want a simple player and
ecasound for most everything else. I'm not sure, but I think these apps
scale the volume internally rather than messing with the mixer controls
...
BTW, I think I also had a "lock up" problem
when trying to change clock source
between internal and SPDIF (back to internal?), using envy24control. I had to
"kick it around" before the change would "take". I'm not sure if
SPDIF stuff
works, or is supported. I had other problems to fix, so I didn't pursue that
any farther. Sorry. I have a Johnson J-Station (guitar amp modeler) which
could provide SPDIF outputs, but I'm currently running its analog outputs
through a Peavey RQ-200 6 channel mixer into the Audiophile-2496 analog PCM 1
& 2 inputs. That works well enough, and I'm not desperate for more channels.
Converting A/D/A/D doesn't seem that bad, but I haven't listened that
closely. Good enough for the likes of me. I can put off wrestling with SPDIF
for a (long?) while. The engineer in me likes to see everything work.
I have vague memories of problems like this being fixed in more recent
releases.
