-==== How to set up sound from speakers? ====
+==== How to set up sound? ====
+Lubuntu 12.10 have sound (playback and record) out of box. In case you changed settings and sound don't work anymore, try to reset settings:
+<code>
+alsaucm -c tegraalc5632 reset
+</code>
+For other systems use following guide:
   - REBOOT you machine to be sure it was not resumed (sound doesn't work after resume yet)
   - run audio playback
   - start alsamixer
   - common stuff
-    * remove mute state from "Stereo DAC"
+    * remove mute state (press **m**) from "Stereo DAC"
+    * remove mute state from "Line" (or "Master", depends on kernel version)
   - speakers settings
-    * remove mute state for "Speaker Mix DAC2SPK", "Int Spk", "Line"
+    * remove mute state for "Speaker Mix DAC2SPK", "Int Spk", "Speaker"
     * set "SpeakerOut Mux" to value "Speaker Mix". NOTE: some people get sound from speakers only when "SpeakerOut Mux" is set to "HPOut Mix". I you have suspended before reboot as sound doesn't survive suspend yet.
   - headphones
-    * remove mute state for "Headphone", "HP Mix DACL2HP" и "HP Mix DACR2HP"
+    * remove mute state for "Headphone", "HP Mix DACL2HP" and "HP Mix DACR2HP"
     * "HP Left Mux" set to "HPL Mix", "HP Right Mux" set to "HPR Mix"
   - enjoy, and don't forget save changes with **sudo alsactl store**

 If you are using Nilfs2 as filesystem you need to make sure nilfs_cleanerd is running, if it's not running the disk will keep filling even when you delete files. You may need to install nilfs2-tools and reboot / remount the partition.
 If you end up with a full partition you do not have any possibility to install nilfs2-tools it still possible to clean it, if you installed on SD-card just move it to another computer with nilfs2-tools and make sure nilfs_cleanerd is running. If you installed on internal emmc you will need to install a distribution on SD card and from there mount and clean the internal emmc.
