Sound issue

[Komachi]

So when I run OR sometimes for just a few minutes, sometimes for longer, OR starts popping and crackling VERY annoyingly. I dunno WHAT is causing it nor how to fix it. Any ideas? Sound card wise, I'm running just some generic plug-n-play card that I cannot discern a brand off of. This is a fairly new problem, though. Running whatever the current experimental version is, and it's been going since before 0.9, so.

Same here with my Audigy 4 on Win7 x64. The last version without problems was x1613 (sound is ok in MSTS).

I have a SupremeFX2 card and nearly all sounds are crystal clear. The exception is one EMD 567 soundset that while clear in MSTS gives me pops and crackles in OR. This started before 0.9 was released, probably with X1614.

Try a hundred car freight, and let it go by in #4 view. Do you have full sounds for the entire length of the train?

That is not what this thread is about. This is about poor quality sound with pops and crackles in the playback.

Yes it is. It's all related. After the sound drops out during a run-by there are still some occasional pops and crackles. Possibly the same bug? In some previous releases the sounds did not drop out during run-bys, and now it does. Coincidentally the issue regarding popping and crackling that was brought up by the original poster has arisen also. So, to the original poster, can you try a hundred car freight and let it go by in #4 view. Do you have full sounds for the entire length of the train?

I have a 104 car train with 4 engines, Have done 2 consecutive view 4 run-bys. No loss of sound in either of them for the whole length of the train and no pops or crackles in any sound afterwards. It is only the one soundset that gives me the pops and crackles.

Hi Baldwin,
If the 567 sound set you're using is 567sound.zip from the library, there is an error in the sd18eng.sms file. A close bracket is missing and should be inserted between lines 157 and 158 - ie just before the ScalabilityGroup 0 'Skip' lines.

This may, or may not, be the source of your problem, but it's worth a try!

Cheers,
Ged

Thanks Ged, but not that soundset. These are the BLW F3 Monon set which have their own sounds. They run fine in MSTS, just not OR since just after the 0.9 release.

Thank you for checking that, and hope you're situation gets resolved soon. Yes it can be frustrating, but the OR team is doing a splendid job of getting it all worked out!

And this just in...
Some code was just committed to the trunk which fixes many of the remaining sound issues! It should be included in the weekly update that comes out tomorrow. See if that helps.
