I'd probably take the mics out first. > outputs.mic2_source=dac-6:7 > outputs.mic2_dir=input-vr50 > outputs.SPDIF_source=dig-dac-0:1 > record.adc-2:3_source=mic2 > record.adc-2:3_mute=off > record.adc-2:3=120,120 > outputs.mic_sense=unplugged > outputs.line-in_sense=unplugged > outputs.line_sense=unplugged > outputs.mic2_sense=unplugged > outputs.master=126,126 > outputs.master.mute=off > outputs.master.slaves=line > record.volume=120,120 > record.volume.mute=off > record.volume.slaves=adc-0:1,adc-2:3 > outputs.mode=analog > -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
