pchdtv 3000 cx88 audio very very low level

From: Greg Stark

Is this video4linux list still active? I see very little traffic on it. Is
there a better place for questions about v4l drivers for the pchdtv 3000 cx88
NTSC tuner?

I have it working fine but the audio is extremely low level. Even if I boost
the line-in level and the master output level to max on my sound card it's
barely audible over the background static.

Is there something wrong with my card? Or with my drivers?
