Summary:                    Audigy2 Platinum: very low volume (both in and out)
Description: 
Both the input and output levels of my Audigy2 Platinum seem to be very low
if compared to the same card with Windows (win98se). For example, I
connected an external source (a MD player with very loud music in the
disc) to the optical input, then to the aux input, then to the aux2 input.
With the mixer settings to 100% the input level still does not go over
20-25% of the maximum amplitude (while with Windows I have to lower the
input level or it will be too high). The same thing applies to the output
level of my analog speakers. [I must be *very* careful when I reboot with
Windows and must not forget to turn the volume knob from 10 to 2]. I had
exactly the same problem when I used the emu10k1 drivers from sourceforge.

I tried to record a CD track (1st mov. of 5th symphony by Beethoven :-))
with a CD player with the optical output connected to the input on the
audigy2 and IEC958 Capture at 100, then I tried connecting it to the RCA
connectors (analog inputs, 100% volume), then I recorded it playing the CD
in my CD-ROM reader (connected to the audigy2 "Audigy CD" digital input,
100% volume), then I ripped it with cdparanoia. These are the results
(well, I think I went wrong with "very low level". It appears just to be
"lower".)

arecord (IEC958 optical input, Sony MXD-D1)
Maximum amplitude:     0.835510
Minimum amplitude:    -0.828491

arecord (Aux IN 2 on the front panel, Sony MXD-D1)
Maximum amplitude:     0.727905
Minimum amplitude:    -0.715240

arecord (AudigyCD digital audio CD input, LiteON something DVD-ROM)
Maximum amplitude:     0.832703
Minimum amplitude:    -0.828522

cdparanoia:
Maximum amplitude:     0.933868
Minimum amplitude:    -0.923676

As for the comparison windows vs linux, I'll reboot in a few minutes then
I'll post the results.
