No, I definitely see a 4dB discrepancy between peak sine wave level
and the indications on PPM and VU (+10). The meters read higher than
the actual signal level. The sound card is an M-Audio Audiophile 2496
if that is any help.

See this screen shot for the situation  CBS loudness gain is +18, VU
meter gain is +10.
