+======  OSS ======
+Sound is NOT built into base of MicroCore, TinyCore or CorePlus, sound is implemented via extensions.
+Assuming you are a newbie, select ossxmix from the Apps and choose onboot. On reboot, you are likely to have sound.\\
+If you have installed a desktop eg LXDE, you can drag into your desktop folder using your filemanager, the file is called ossxmix.desktop.\\
+Your desktop icon is named
+<code>
+OSS_GTK2_mixer.
+</code>
+The desktop (or icon) files are in
+<code>
+/usr/local/share/applications
+</code>
+Otherwise, you can click on empty desk space, choose Applications and name of mixer is called
+<code>OSS_GTK2_mixer</code>
+If you prefer commands, open a terminal and run command
+<code>
+ossmix
+</code>
+For more advanced users, if you do not want a GTK download choose OSS from apps and reboot.
+===== OSS versus ALSA =====
+Warning: This is written for newbies, its not meant to be a pure recommendation but \\
+is the personal opinion of aus9 to minimise forum posts where newbies can't do something \\
+because they may be trying to use OSS when something might be better or vice versa.
+   * If you need skype --> ALSA (and suggest no Pulseaudio) \\
+   * If you need to change sound devices on-the-fly gui --> Pulseaudio (front end to ALSA) \\
+   * If you need to change sound devices no gui -->  ALSA \\
+   * If you need easier surround sound  -->Pulseaudio  \\
+   * If you like command mode surround sound --> Try OSS \\
+   * If you need a sound modem (dial-up) plus normal sound out --> Likely to be ALSA \\
+   * If you need to use a webcam builtin mic --> Try OSS then ALSA \\
+   * If you need to play high quality sound files --> ALSA\\
+   * If you have a Intel device, that needs a tweak --> ALSA
+   * In case you have an ISA sound card or a very old CPU, alsa may be your only choice.
+OSS is easier to setup, but fewer people use it so you may not get the support you are looking for.
+See surround sound for a link to a forum.
+ALSA is better suited to those with "better" sound devices or multiple sound devices or \\
+sound devices that need tweaked settings.
+As I have an intel device, that needs a tweak, multichannel sliders do no appear in my ossxmix image as \\
+OSS appears to not know how to handle my sound device.
+However, OSS is still easiest of the the two to setup for persistence so try OSS first please unless my list rules \\
+OSS out.
+good luck and [[setting_up_sound|click here for ALSA wiki]]
+=====Remove ALSA=====
+If you have previously installed ALSA remove those packages from onboot

+===== Checking tcz loads ok on reboot =====
+When first loaded you may like to open a terminal and run command....ossinfo to see if your card is detected.

+If ok, you may wish to open cpanel...click on system stats then modules to see what modules are loaded.
+{{wiki:twid_25_cp-mod.jpeg}}
+You may like to navigate to /usr/lib/oss/conf and related folders to tweak any setting you may need
+===== Mixer levels =====
+Newbies might like to install a gui mixer called ossxmix.tcz.
+In the following image, I have ossxmix started and moved my media player, vlc over the mixer panel so I could snapshot my terminal showing the command to run, the mixer panel and my media player.
+{{twid60_ossxmix2.jpg}}
+You may not have front connectors, as this is a tower and not a laptop.
+The Master volume slider controls all.
+Next image is un-ticked the channel lock so I can have different volumes left versus right.
+{{twid_61_ossmix3.jpg}}
+===== Media player may need tweak =====
+If you run a media player gui, like vlc, you will need to tweak it to use OSS as that won't be its default.
+===== Persistence =====
+If you have come from ALSA persistence, please remove all those settings as per {{wiki:setting_up_sound| ALSA wiki}}
+and do a full reboot before doing any OSS stuff please.
+If you need OSS persistence use root powers to edit your
+/opt/.filetool.lst to add line
+^usr/lib/oss/etc^
+If needed, add other conf lines to above file, if you needed to change any.
+Then reboot, with backup, to test its ok.
+Note, if you use a media player, gui, its settings are likely to be stored under /home/tc so no extra files need to be added
+to a standard TC user.
+(warning ...aus9 is not an oss or alsa expert)
+===== Tweaks =====
+Testing without reboot.\\
+Open a terminal and run command
+<code>
+sudo soundoff
+</code>
+Make changes to /usr/lib/oss area then
+<code>
+sudo soundon
+</code>
+Try at own risk, please watch out for any typos in your backup .filetool.lst etc
+If you know your sound card can do higher quality sound output tweak
+^/usr/lib/oss/conf/osscore.conf^
+Remove # so below line becomes active on next boot \\
+src_quality=4
+^/usr/lib/oss/conf/oss_hdaudio.conf ^
+For those with high definition audio (intel), consider trying out a jack sense (3.55mm connector in the coloured holes) \\
+hdaudio_jacksense=1
+===== Surround sound  and OSS **forum**  extras=====
+For surround sound click on the forum link and enter this string as a search please, as I have attempted to provide 2 links to it\\
+but its borked
+^HOWTO: 5.1 Surround sound with OSS4 ^

+===== Webcam =====
+To get your webcam working in TC, is not fully discussed in this wiki.\\
+For my cam, on an usb lead, I need to use a module called uvcvideo so its sufficient for me to load\\
+v4l-dvb-3.0.21-tinycore.tcz
+My cam does not appear in
+<code>
+/usr/lib/oss/etc/devices.list
+</code>
+As its on a lead, I did a full reboot and then usb webcam tab appears in mixer pane
