Comment (by myth@…):

 For what it's worth you are not alone with this issue.

 I had the same thing in 0.23 fixes and now with every build of 0.24 I have
 tried.
 In 0.23 I wasn't using storage groups, so just used mplayer for mkv files.
 With 0.24 I have moved to storage groups, but have been able to work
 around it by unticking the box that says my amp supports DTS. As I'm using
 an HDMI connection myth just decodes the DTS then sends multi-channel PCM.
 Not ideal but as it's a usable solution I hadn't spent any more time on
 it.

 Other formats I've tried with DTS in seem to be OK for me, it's just mkv
 files.

 Logs don't suggest any problems, myth seems to think it is streaming the
 DTS data OK.

 In case it helps, the frontend in questions is a diskless Zotac IONITX-A
 (so VDPAU for all video), 2GB RAM, running 64bit Gentoo. OS is recently
 updated (with no change in the behaviour above), though I'm still on a
 2.6.31 kernel (the hastle I had getting HDMI audio working has put me off
 updating for the time being) I have recently upgraded the nVidia driver
 though, which has not changed this behaviour either.

 Regards,
 Graham
