Output jack adjacent to firewire connector works; Wave Surround
volume control functions normally.
The next jack over also works; its left and right channel volumes
are controlled independently by Wave LFE and Wave Center.
The output levels of all these jacks seems 12db lower than the main
output of my audigy1. I suspect this is normal and has something to
do with the 12db boost option I read about. The sound quality seems
good. The noise floor seems lower than the old card.
oh thanks, that's good to know.
All controls may be turned to zero save for Wave LFE, Wave
Center, or Wave Surround; it will work fine, and the other
controls, like Master and PCM, have no effect.
this means that ac97 is not routed as audigy1. perhaps a different
bus is assigned.
The next jack is always silent; the Wave control (my guess as to
what should be controlling it) does nothing.
what kind of output is expected on this jack?
However, the livedrive
headphone output _does_ work, and _is_ volume-controlled properly by
Wave. (Its output level is no higher than the other two jacks,
which reminds me of something I read in an audigy1 review - that the
headphone output was weaker than the line1 output.)
Both joystick and livedrive MIDI outputs work, but neither MIDI
input will read anything. I've tried plugging in a keyboard and also
directly looping one of the outputs to one of the inputs, to no
effect.
this might be a bug of the driver, but not sure, atm.
could you check whether interrupt counts increase when you receive a
midi input?
Livedrive RCA-SPDIF output works, but it's possible to get weird
distortion (sounds like chimey bell tone things accentuating the
music) if I configure the mixer certain ways. What's needed to make
it work is to simply turn up Wave; everything else may be off. If
I turn up PCM the weird chime distortion starts. (Addendum: I
can't reproduce this reliably, so it may depend on other state.)
hmm.. it seems that on audigy2, ac97 playback volumes should be kept
zero.
arecord seems capable of recording audio that I'm playing from a
mp3, at the exact level I'm playing it.
So, that's all the testing I've done thus far. Maybe somebody will
find this useful. Meanwhile, I'll try to get the MIDI input going
by... umm. Staring at it real hard, maybe? Oh well.
thanks for your tests!
perhaps i'll get audigy2 for tests, too, and will take a deeper look.
ciao,
Takashi
