 +Install alsa-config.tcz and alsa.tcz
 +
 +Install alsamixergui.tcz (optional)
 +
 +Set the volume control on the front of the speaker about 1/3 of the way up
 +
 +Run:
 +<code>alsactl init</code>
 +
 +This produced a slight thump as the card was found and initialized. That command
 +also unmuted the speakers and set the mixer volumes at sane levels.
 +
 +Run:
 +<code>speaker-test [-Ddefault:1] -c2 -t wav -l1</code>
 +
 +If all went well, you should hear the phrases  "Front Left"  and  "Front Right"  from
 +your left and right speakers respectively.
 +
 +Run:
 +<code>sudo alsactl store</code>
 +
 +Run:
 +<code>echo alsactl restore >> /opt/bootlocal.sh</code>

 +Although I use HDMI as the main theme in this section, it applies to all users that need it and model=string in other sections or index strings does not resolve sound issues for you.

 +
 +Now reducing my aplay command to bare essentials, it reads
 +<code>
 +card 0, device 0 (analog) 
 +---subdevice 0
 +card 0, device 1 (digital)
 +---subdevice 0
 +</code>
 +
 +But lets pretend you see output for digital and it reads
 +
 +card 0 , device 1   (hdmi)\\
 +---subdevice 0
 +
 +as the first subdevice tends to be hdmi, we can drop reference to it in the asoundrc but if you need it, add the extra line below device (number)
 +^subdevice (number)^
 +
 +We next create a file to be saved as /home/tc/.asoundrc with contents in a code box for display purposes only
 +
 +<code>
 +pcm.!default { 
 +type hw 
 +card 0
 +device 1
 +} 
 +
 +ctl.card0 {
 +type hw
 +card 0
 +device 1
 +}
 +</code>
 +
 +The first string pcm......!default is telling alsa....try this device first for any application wanting to use sound.
 +
 +Now as we newbies, instead of learning how to stop and restart alsa, we cheat and logout and choose "Exit to Prompt", then run your mixer to see if you have HDMI showing up. If it does do a reboot and retest.
