Track dynamic range
I have recently gotten Ardour working on my Ubuntu Studio workstation, after using Audacity for several years. The only problem I have is that I am unable to fully utilize the dynamic range of my tracks. I have a mixing board feeding a PCI SoundBlaster card through the Line input. It works, but I cannot seem to record at a level higher than roughly -8 dB. When I try raising the mixer output, it just starts clipping even though it looks like I have all of that headroom.
To rule out the mixer/sound card/Ubuntu, I tried recording in Audacity and I am able to saturate both channels (if I wanted to!) This leads me to believe that the problem is somewhere between JACK and Ardour, or perhaps in the ALSA handoff to JACK. Could anyone point me to the setting(s) I can look at or suggest another approach?
