Revisione di Master Channel has no Effect on the Sound Card del Lun, 04/14/2014 - 03:51

Le revisioni permettono di tenere traccia delle differenze tra le diverse versioni di un contenuto.

If the Master channel has no effect on the sound card, then the default control has to be switched. Use gnome-alsamixer or alsamixer to test. GNOME does not provide a means to switch default mixer controls, so here is how to switch the mixer(s) affected by a multimedia key although the volume bar (screenshot attached) will stop appearing:

  1. Open the Trisquel menu.
  2. Pick System Settings.
  3. Go to Keyboard.
  4. Switch to the other tab: Shortcuts.
  5. Click Custom Shortcuts.
  6. Click the plus button.
  7. Give the shortcut a name like "PCM up".
  8. Enter a command, like "amixer set PCM 1+". This will raise the volume as much as alsamixer would after pressing the up arrow key. 2+ is also suitable, but 5+ is probably too much.
  9. Apply.
  10. Click Disabled.
  11. Use the multimedia key as though it would increase the volume.
  12. Press Reassign.
  13. Repeat steps 6 through 12 for the "PCM down" shortcut, but use a minus instead of a plus symbol in step 8, i.e., amixer set PCM 1-
  14. For another control like Headphone, repeat these steps, but hold down the Ctrl key while using the multimedia key.
