DTS audio cd is not supported by mplayer.
Since you think DTS in AVI always has problem, then we assume your
mplayer always has problem of DTS passthough. Then what about AC3
passthough?
What kind receivers did you use? Can them decode DTS/AC3 correctly by
other any player on your system? Are you using coaxial or optical
output of ALC655. What's the ao setting of your mplayer? ALSA need to
set some ao sub-device to passthrough correctly. You may try this:

-ao alsa:device=spdif
or
-ao alsa:device=iec958
or
-ao alsa:device=hw=0.4

Where the 0.4 can decided by output of cat /proc/asound/pcm
