 Possible Solution: Edit ''~/.mplayer/config''
 <code>heartbeat-cmd="xscreensaver-command -deactivate >/dev/null 2>&1"</code>
+===== Login issue =====
+When using xdm, login fails sometimes with error message ''... Unable to establish ICE listener...''
+  * append ''rc.local'' <- ''rm -rf /tmp/.ICE-unix/*''
+===== Audio issue when using ALSA =====
+The solution is [[https://docs.slackware.com/howtos:hardware:sound_problems_on_slackware|here]].
+    * in short, ALSA using the HDMI output as default
+    * use alsamixer, [F6] select the card (the one that is NOT HDMI) and make sure output is not muted
+    * use aplay -l to identify the card/slot# and device#
+    * use ''aplay -D plughw:<card/slot#>,<device#> <WAV file>'' to test
+    * modify ''asound.conf'' in etc or ''~/.asoundrc'' to fix this (sample below) <file text asound.conf>pcm.!default {
+        type hw
+        card <card/slot#>
+   }
+   ctl.!default {
+        type hw
+        card <card/slot#>
+   }</file>
+===== Low volume when using ALSA =====
+As seen [[https://alien.slackbook.org/blog/adding-an-alsa-software-pre-amp-to-fix-low-sound-levels/|here]]...
+Check ''asound.conf'' in etc: <code>
+  pcm.!default {
+      type plug
+      slave.pcm "softvol"
+  }
+  pcm.softvol {
+      type softvol
+      slave {
+          pcm "dmix"
+      }
+      control {
+          name "Pre-Amp"
+          card 0
+      }
+      min_dB -5.0
+      max_dB 20.0
+      resolution 6
+  }
+</code>
+Sometimes need ''type'' in ''pcm.!default'' to be ''hw''
