I have a strange problem when playing back DTS encoded cds on my computer, when streaming the signal digitally through my sp/dif the music plays too fast and grown ups sound like children while children becomes all squirrelly. However it sounds ok if I choose to decode the signal and play it back analog.
I't doesn't matter which player I use, I've tried Mplayer Classic as well as Power DVD 5.
Have anyone got a clue what to do?
Hmm. I don't know too much about this, but could this happen if the clock was too fast? You should be able to either sync your soundcard's digital input to the clock of your DTS player (ie, use the player as the master/external clock), or set your soundcard as the master with the right clock. If it's playing too fast, maybe it's stuck at 96KHz, but DTS encoded material is only sampled at 48KHz?
... or maybe I'm totaly off.
DTS CDs are encoded at 44.1KHz. Whatever's decoding your SPDIF stream must be assuming it's regular old 48KHz DTS. I've heard the problem before. Never found a fix
Maybe the soundcard is a resampling one, and even when it doesn't resample, in order to play DTS, it is still stuck at 48 kHz (that is the hardware reason for resampling).
Does your receiver support DTS encoded materials?
I was able to play dts encoded in 48 khz with Power DVD, but I couldn’t play DTS Audio. Actually, DTS Audio is encoded in 44.1...
I have found two solutions.
The first solution was to use my very old CD player with the digital output (sp/dif) feeding my decoder.
The second solution is to feed in 44.1 my decoder with foobar thru asio driver (in order to be sure to keep each bit accurate). You must disable all digital treatment (DSP, dithering).
You can rip your DTS audio like a normal CD (freedb generally have the right names) and play it as a normal wav.
It works well now on my laptop, when a dts or ac3 file is played on my playlist, my decoder directly detect it.... but I still need Power DVD in order to play DTS and ac3 encoded in 48.
Hope this help.
Hi there!
I have SB audigy... I have the same problem, 48khz DTS ok, 44.1khz DTS audio is not... I tried foobar2000 but i heard only pink noise... where can i get ASIO driver for my soundcard? OS: win XP pro..
All thing are disabled such as DPS, dither, etc...
i cannot find anywhere....
unfortunately if you have a resampling soundcard (creative have won no friends from this design flaw), there's not a lot you can do.
either:
it doesn't resample, it just plays back at 48 instead of 44.1, in which case you get super-fast sound
or:
it resamples, causing the DTS data to b0rk completely, giving white noise at -12db
the problem is that DTS is a simple CDDA stream. the soundcard thinks it's streaming a PCM wave rather than DTS data.
if you have a CD/DVD player with spdif, use that, or get yourself a soundcard that doesn't resample everything to 48k
