Hrm, I have two problems here. 1) This machine does not have X11, and cannot have X11 on it. Let alone KDE. 2) I don't see "IGain" in the alsamixer at all. I think if I turn down the slider all of the way for "Line-In" I don't get any recorded audio from LINE-IN. When I examine the asound.state file, the line controls are labelled thusly: name 'Line Playback Switch' name 'Line Playback Volume' comment.item.4 Line HOWEVER, I see: control.24 { comment.access 'read write' comment.type ENUMERATED comment.item.0 Mic comment.item.1 CD comment.item.2 Video comment.item.3 Aux comment.item.4 Line comment.item.5 Mix comment.item.6 'Mix Mono' comment.item.7 Phone iface MIXER name 'Capture Source' value.0 Mic value.1 Mic Which seems to imply I can change the SOURCE of captured audio. I think I understand what you've done though, and I could probably figure out how to replicate how you've setup your volume controls with alsamixer's understanding of how things are configured on the sound hardware. But it will be alot of trial-and-error. :( Alas, this setup is used during the day so such experimentation will have to wait. Maybe some kind soul knows what "IGain" is under the alsamixer? Maybe it's "Capture Volume"? OK, maybe I can get what I want my manually editing the asound.state file and doing an alsactl restore... So much for the GUI! :) I'd really like to see the source document referenced by the engineers who setup the volume control software for ALSA/OSS, because the appearance is one of total chaos and disorganisation. This isn't rocket science, and we aren't talking about THAT many inputs, outputs, and mixers: there's a microphone input (mono, with selectable +20dB boost, and maybe optional power), line input (stereo), CD audio (stereo), PCM wave output (stereo), master output level (stereo). So what do I see under alsamixer? A dozen sliders, some with tri-state toggles in addition to levels, with additional state for "record" or "capture", with non-obvious interdependencies when I switch "sources". Crazy. Even the Dark Lord could not have designed a more intentionally obfuscatory interface to audio hardware, =MB= -- A focus on Quality.
