Uncheck the option:

Use internal volume controls
MythTV can control the PCM and master mixer volume.  If you prefer to 
use an external mixer "program, then disable this option.

Although that means that you always have to use an external program to 
change volume.

Probably what you want to do, instead, is quit messing with amixer and 
do what you've told Myth you plan to do--use internal volume 
controls...  Use F11/F10 to raise/lower volume.  After configuring Myth 
to use either the PCM or Master control, change the other control with 
amixer to 90% or so and adjust the Myth-controlled control using volume 
up/down (F11/F10).
