View Full Version : LG BH200 DTS audio help
iamlilc 06-13-08, 01:17 PM Everytime I try to play a Blu-Ray disc with DTS-HD MA, I don't get any sound whatsoever and the picture freezes.
I first had my player connected through HDMI to my Sharp Aquos TV and it didn't work, so then I bought a receiver that had a DTS decoder a connected it through toslink and it still doesn't work..
I also have the lastest firmware and driver.
Can someone tell me what I am doing wrong?
david.p 06-13-08, 02:34 PM What is audio setting is the BH200 using? I'm also connected to a receiver over optical toslink and have the BH200 set to PCM Stereo for HDMI and DTS Re-encode for SPDIF.
Are you seeing the problem with one particular disc or multiple discs?
iamlilc 06-13-08, 03:20 PM I'm pretty sure I tried all the combinations, but the manual said to use DTS re-encode so that's the one it's on for both HDMI and SPDIF.
It's only a problem on discs with the DTS-HD MA audio option (ie. Live Free or Die Hard, The Eye, Both Fantastic Four Movies). But on Live Free or Die Hard and Rise of the Silver Surfer I just changed the audio to Dolby Digital and it works fine, but for The Eye and Fantastic Four the only english audio tracks are in DTS.
Does your set-up work with DTS audio tracks?
bradavon 06-13-08, 05:16 PM Could they be faulty discs? I appreciate unlikely. Have you tried cleaning one of them? Do they play in other players? Have you tried the January firmware? I only ask in case the April firmware didn't install correctly.
To clarify do you mean DTS or DTS-HD discs? Have you tried DTS? Either on DVDs or on HD-DVD/BD? Does (standard) DTS work? DTS and DTS-HD aren't the same.
There is no reason why DTS-HD should not work but Dolby soundtracks do. For testing purposes have you tested using Primary Pass-thru and PCM Multi-Channel for DTS-HD discs?
All three should give you Multi-Channel DTS:
* Primary Pass-thru - The DTS Core found inside DTS-HD Bitstreamed to your Amp to decode, your Amp will detect it's receiving a DTS signal.
* PCM Multi-Channel - The DTS Core decoded and sent out as PCM, you'll find the Amp doesn't detect it as DTS (as it's already been decoded) but it should sound identical.
* DTS Re-Encode - All audio transcoded (i.e - re-encoded) into DTS. I'm not sure if it's already DTS whether it still gets transcoded but regardless it's always DTS, your Amp will detect it's receiving a DTS signal.
You're quite right DTS Re-encode is the best option for Amps with Optical, it's worth testing the other options though. You may have a broken player and it will help narrow down what aspect is faulty. DTS Re-encode enables the on-board DTS transcoder for instance.
Once tested put it back to DTS Re-encode. This is particularly crucial for TrueHD over Optical.
It sounds like the HDMI is going directly into your TV. I too use HDMI to my TV and Optical to my Amp. I've set HDMI to PCM Stereo as that's the native format of "Stereo TV Speakers" but in reality it won't make any different the end result will still only be PCM Stereo.
allargon 06-13-08, 05:49 PM What receiver do you have? Many "DTS receivers" only decode 768kbps DTS not the full 1.5Mbps DTS. This could be a problem.

Really? I've never come across any.
A DVD with (Half-rate) DTS will answer that one.

The discs are not faulty because they do play on the PS3 and if I change to anything but DTS it works perfectly fine. I didn't notice if DTS played when I had the Jan firmware, but I installed the April firmware a second time and everything seemed to install fine.
I tried a standard DVD and regular DTS doesn't work either. I get the same result, but instead the DVD freezes completely whereas the BD I can at least change the audio or go back to the menu.
When I change the setting to Primary Pass-Through all I get is a static sound. PCM-Multi Channel does the same thing as PCM Stereo & DTS Re-encode - No sound and then freeze.
Shouldn't DTS come through my TV speakers even if I didn't have a receiver?
I just have a cheap Sony receiver that came with an all-in-one system, but it does have a DTS decoder.
I'm assuming it's either a software problem or a hardware problem since I can't get any sort of DTS audio from it.

Your TV won't play DTS unless you send the audio as PCM or (duh) analog in via the stereo cables. Most HDTV's can decode Dolby Digital but AFAIK not DTS.
How old is your receiver? I have a cheap ($97 sale for the receiver + 5 speakers and a sub), but recent Sony receiver as well. It still decodes full bit-rate DTS. (Bravadon, several people had issues with the 2nd gen Toshiba HD DVD players as they send out full-bitrate DTS from their Toslink just like the BH200.)
Iamlic, please set everything to multichannel PCM. Honestly you may have a faulty unit. You did try a different HDMI cable right?
iamlilc 06-16-08, 11:01 AM I'm using the receiver that came with my Sony 1-Disc HDMI Micro Home Theatre System (DAVIS10). I'm using toslink from my receiver to the player and HDMI from the player to my TV.
I tried setting HDMI to PCM multichannel, but what do I set SPDIF to? There is no PCM multichannel option for that one.
No, I haven't tried a different HDMI cable..
bradavon 06-16-08, 02:43 PM Sadly it sounds like your is faulty, to me.
You cannot even get DTS on DVDs to work.

Me neither, I don't think you can even get the DTS logo without supporting 1.5, which is part of the DTS standard.

Well that's just great.. I guess i'll call up LG. :mad:
oilblue 06-20-08, 03:48 AM Just to eliminate some other possibilities, set things like this:
- HDMI = PCM Stereo (your TV most likely has two speakers, so stereo is as good as it'll do anyway)
- SPDIF = DTS Re-encode (you've indicated your receiver can decode DTS, so you should be set)
That should be the best configuration for your current setup (HDMI to TV; SPDIF/TosLink to DTS receiver). Actually matches our setup exactly.
Note that the HDMI and SPDIF settings are not completely independent. Setting one *can* affect the other. For example, here's a footnote from the audio support table in the manual:
The [PCM Multi-CH]/[Primary Pass-Thru] setting of the [HDMI] option and [DTS re-encode] setting of the [SPDIF] option cannot be set together. If you set the [HDMI] option to [PCM Multi-CH] or [Primary Pass-Thru], the [SPDIF] option is set to [PCM Stereo] automatically. Also, if you set the [SPDIF] option to [DTS Re-encode] and the [HDMI] option is set to [PCM Stereo] automatically.
So, contrary to earlier suggestions, do not set HDMI to PCM Multi-Channel or Primary Pass-thru. Doing so would only downgrade the best connection you currently have--SPDIF/TosLink to your DTS capable receiver.
Hope that helps.

I only said that for testing purposes :).
oilblue 06-21-08, 01:34 PM Why'd you assume I was referring to you? :) It was more this comment, that suggested changing the HDMI settings:
Iamlic, please set everything to multichannel PCM. Honestly you may have a faulty unit. You did try a different HDMI cable right?
Doing that would *not* have helped the optical out.
That's all I was getting at...but I didn't think it was necessary to quote directly (felt like pointing fingers, and that wasn't my intention). I probably should have though, just to avoid misunderstandings like this. Oh well.
Cheers.
