I will tell you that (from what I understand) it lists things that probly don't even pertain to _your perticular card_. So that makes trying all the settings more confusing. Also, I have found that "unmuting" or toggling "capture" modes on certain settings can cause a high pitch sound. So I would suggest that you already prepare (in another shell) the command that will restore your original "state". My main "state" file is located at /etc/asound.state. So I will use that as the example. If you get in trouble, do... "alsactl -f /etc/asound.state restore" (no quotes of course). Here's the catch though (at least on my set up). I found that the "/etc/asound.state" file changes every time I change my alsamixer settings (even if I'm _not_ root). So I would suggest that You move the "asound.state" to a different location and do... "alsactl -f /NewLocation/asound.state restore" if You get into any trouble. Once I get the right settings, I save the file to a different location by doing (I hope the syntax is right) "alsactl -f /NewLocation/NewName.state store". With that quirk of it always writing over the original "asound.state", I have "/NewLocation/NewName.state" always handy. In fact, I have it load during bootup because the original /etc/asound.state is always different with every session. But you can do what you need to do. In alsamixer, I toggle "mute/unmute" with the "m" key (if it's muted, you will see "MM" at the top of the slider)... toggle "capture" mode with the space bar (the "-----" above a slider indicates it has a "capture" mode, and the word "CAPTUR" above slider means it's activated)... increase volume sliders with the "up" and "down" keys... and move from slider control to slider control with "left" and "right" keys. Good luck, Rocco
