I have searched through threads and have not been able to find much information on this so I was just wondering if Amir (I think that is his name) or anybody else has posted an official date for the audio issue fix.

I know they are working on a DTS patch but I don't know if this will fix the problem or not. I think the DTS patch will convert everything to DTS and allow 1.5 MBPS instead of the lower 644 kbps (or something like that) but if it is a problem with the code compressing the sound not sure if this will fix it. I have read that a few people including Kris Deering.

Either way I just want to see this problem fixed.

No official date. The patch has been completed and is likely undergoing thorough testing to make sure it doesn't cause unexpected problems. (One recent game patch hosed some consoles and created a lot of negative buzz.)

In the meantime, try alternate audio tracks on discs that offer them. There is a lot of variation between titles, and I've found DD+, DTS, and TrueHD tracks that sounded very good and others that were disppointing.

Glad to know it is finished and in testing. I hope it comes out soon.

From what I have heard the TrueHD tracks don't have the same issue so right now I am trying to buy movies with that option.

Hopefully we get an update some time soon.

Thanks,

Rheal Dubreuil

Actually, this isn't correct. Amir, posting on the insiders forum, stated just before Christmas that the bug fix for DD+ was still a work in progress. So the patch is not completed and is not undergoing testing as you stated.

Supposedly the feature to output DTS was completed. When asked about the release date for that, Amir stated there was "nothing concrete".

Wnorris,

Thanks for clearing that up. Where is this insiders forum you mentioned?

Thanks,

I watched snakes on a plane on my 360 HD DVD drive last night and selected DTS ES, and my reciever displayed DTS ES as the output and it sounded great.... maybe they implemented it already?

There is no issue with the drive ! Its the Software that decodes the HD-DVD Sound, that is corrupted and needs to be fixed.

So playing a standard DVD (As Snakes on a plane) will not give you any problems.

Yes as far as I know the normal DVD software has no sound Issues. It is just the HD-DVD software that has some sounds issues. As far as I know there are two things in the works one patch and one upgrade / extra feature depending on your point of view.

Upgrade / extra feature is:
----------------------------------
Addition of DTS (I think that will include the 1.5mbps bandwidth but will only sound good if used properly)

Patch:
---------
Fix the DD sounds issue with the sounds dropping out.

Are there other upcoming patches / upgrades I am missing? Also are my above statements correct.... that is my understanding of the two being worked on right now.

Thanks and enjoy your HD-DVD drives.

Sorry for me being confused on the issue, I just got my drive and am a noob to the whole issue. So the actual problem is HD DVD's not decoding DTS correctly, as well as sound drop outs?

Let me try ... I am still fairly new and the other threads are just massive. So here is my attempt.. if I am wrong somebody will correct me This is what I believe.

DTS when selected on HD-DVD's will be decoded as Dolby Digital (DD) and it is Dolby Digital that has the drop outs. This is not a fault of the drive but the software used to play HD-DVD's and the fix is being worked on for the DD issue and an update is also being worked on to include DTS that will be output as DTS.

Normal DVD's are played fine with no drop outs and will decode DTS normally so it is not a hardware issue.

Hope that is correct and hope it helps.

I dont have any dropouts, I have terrible dynamic range. If you have Superman Returns watch the SD version in the regualar drive and then watch it on hd-dvd. The planet explosion at the beginning is a very good example of the problem.

The problem I notice is that dialogue is very low. When I turn up the audio level the dialogue gets better but when effects occur the sounds is crazy loud. So the audio isn't even. Is that the same problem ya'll are hearing?

Per knowledgeable Xbox 360 users (not me ), the problem is only with Dolby Digital Plus (DD+) decoding. Apparently the decode defaults to a limited dynamic range (like Night Time mode). When you have the choice of using Dolby TrueHD or dts on the disc menu, then the limited dynamic range problem goes away.

bobgpsr,

Yes that about sums up the problem. Thanks.
