using ffdts for the same file working just fine fine,and my hardware cd player
forwarding dts stream to hardware decoder/amplifier without any problems. I have
over 40 CD's with DTS and AC3 audio tracks so only this bug stoping me to build
mplayer based HTPC.
Using hwdts with moves working fine, the only problem is with wav/audiocd.

Please retry with current CVS. If the problem persists, please upload a sample
to ftp://www.mplayerhq.hu/MPlayer/incoming/ along with a text file containing a
detailed description of the problem (for example dts_unsupported.wav and
dts_unsupported.txt).

Yes, hwac3 does only support passthrough 48kHz DTS audio. Most DTS wav is 44.1kHz and 14bits format, to passthrough them, try put '-ac +pcm' to your mplayer commandline, if it still not decoded by external decoder, try add '-format s16le' or '-format s16be' to commandline, that works for me and my dts wav samples.

I made a patch to make hwdts support dts wav (14bits) stream.
http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2007-November/054881.html

I think it could be applied in 1 to 2 weeks. So the dts wav problem will be resolved.

Resolution:	→ fixed
Status:	new → closed

Fixed in svn r25152, now you can passthrough dts wav with -afm hwac3 or -ac hwdts.
For DTS CD, you can also passthrough it by -rawaudio format=0x2001 additional with -afm hwac3 or -ac hwdts.
