Re: [Gumstix-users] Verdex/ALSA/USB microphone question

[Hugh Secker-W. <hs...@ho...>]

I should have added, you need to use alsamixer to set up the
microphone gains and the playback gains.  To set the gains 
for 'card 2' you do, e.g.:

  root@gumstix-custom-verdex:/media/card$ alsamixer -c 2

It has an ncurses based UI.  
- Use the 'tab' key to select the 'playback' or 'capture' device.  
- Use the left-right arrow keys to select the component.  
- Use the up-down arrow keys to set the gain.
- Use 'ESC' to save the settings and exit.

These settings will (usually) be saved across booting if you 
use the 'shutdown -h now' command to halt the system.
