Ironically, the sgtl5000's high-pass filter was introducing a lot of high-end noise, so running adcHighPassFilterDisable() helped (and it seems that you do have to run it explicitly – it appears to be on by default).
There was still some chirping going on in the low-mids while using line in/line out. This turned out to be what I assume is cross-talk from the sgtl5000's headphone amplifier. Oddly, I found the only way to truly disable it and eliminate the chirps was to change one of the writes to the board in control_sgtl5000.cpp. Changing "write(CHIP_ANA_POWER, 0x40FF)" to "write(CHIP_ANA_POWER, 0x40EF)" did the trick. Neither volume(0.0) nor muteHeadphone() were as effective.
