OK, I got movie in mkv container with following audios:
[mkv] Track ID 2: audio (A_DTS) "DTS 5.1 @ 1.5mbit", -aid 0, -alang eng
[mkv] Track ID 3: audio (A_AC3) "English Commentary", -aid 1, -alang und
which should be great for testing.

1) mplayer -aid 0 -ao alsa:device=hw=1.3 file.mkv
Opening audio decoder: [libdca] DTS decoding with libdca
Stream with high frequencies VQ coding
AUDIO: 48000 Hz, 2 ch, s16le, 1536.0 kbit/100.00% (ratio: 192000->192000)
Selected audio codec: [dts] afm: libdca (DTS-libdca)
==========================================================================
AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample)

Amplifier-tuner displays "PCM" and "[ICON]PLII", audio works

2) mplayer -aid 1 -ao alsa:device=hw=1.3 file.mkv
Opening audio decoder: [liba52] AC3 decoding with liba52
Using SSE optimized IMDCT transform
Using MMX optimized resampler
AUDIO: 48000 Hz, 2 ch, s16le, 192.0 kbit/12.50% (ratio: 24000->192000)
Selected audio codec: [a52] afm: liba52 (AC3-liba52)

3) mplayer -aid 0 -ac hwdts -ao alsa:device=hw=1.3 file.mkv
Forced audio codec: hwdts
Opening audio decoder: [hwac3] AC3/DTS pass-through S/PDIF
No accelerated IMDCT transform found
hwac3: switched to DTS, 1536000 bps, 48000 Hz

Can I provide more info for you?

The [ICON] is that icon presented always as dolby digital logo.
