Bug Description

Binary package hint: audacity

(NOTE: the following problem was solved by opening the mixer, choosing Edit / Preferences, checking the "AC97" and "AC97 capture" options so they would display, and sliding those sliders all the way up. Apparently the mixer ships with AC97 partway down. Someone who knows their way around might look into that. It is NOT an aucacity problem, but something with the way the mixer is shipped in ubuntu, perhaps. I found the hint on the HydrogenAudio forum: http://www.hydrogenaudio.org/forums/index.php?showtopic=46365 )

Since the ubuntu 7 upgrade, when I record (line-in -r mic, both the same) I can't use the full range of values up to 1.0. If the input drives harder than about .35 or .4, it lops off the waveform with a square to, causing full square-wave distortion. The input monitor looks fine, like it's using the full range, but the recorded track is clipped. This happens in both recording programs I've tried.
- I'm using an SB Live 5.1 sound card.
- The problem is the same whether I choose ALSA or OSS devices in the mixer, and the same input devices in the recording program.
- I can record, but at a low level, being careful of the 3.5 ceiling, then amplify it, but this is inconvenient, and as it doesn't utilize the full amplitude range, I suspect it introduces distortion.
- I can pull up tracks recorded before this problem (when I was using gentoo) and the tracks look and play fine, using a healthy portion of the amplitude range.
- I have attached the output from lspci -vv and lspci -vvn as suggested in the instructions.
