was looking at a problem someone had w a Judge Dredd table earlier this year  - I now realize it is happening to me on 3 specific make/era tables so thought it might worth posting a topic

 

Have done all the usual basic steps - make sure ROM volume is up/restart/reboot/delete nvram/even deleted and reloaded game and ROM;   but after working fine for months these 3 games no longer have music or voice.  All my other tables seem ok.  

 

Indiana Jones

Judge Dredd

Star Trek  Next Generation

 

all 3 are Williams 1993  "DCS Sound" so I am guessing there is a conflict somewhere but I can't figure it out

 

I did try to switch from VP8 to a newer VP9 version of Judge Dredd though I don't  know if that caused the problem

 

(the other two were already in VP9)

 

Thanks in advance for any thoughts/ideas.

Those three machines have a common DCS implementation using the first generation of DCS decoders, so that's the common element.  The music comes from VPinMAME, not from VP, so the VP version shouldn't matter.  The very latest version of VPM has some special audio code specifically for those three machines, so if you're using the latest VPM version, you might have found an incompatibility.  If you're not using the latest VPM, you might try installing it and see if that fixes it.

 

(The latest version is the one on sourceforge, I believe.  I think the one on vpforums is the last release version from a few years ago - sourceforge has the development working version that's updated pretty frequently, but as a result hasn't been tested as widely.)

Thanks for the reply (and explanation).  I only have the latest version VPM from here and may explore a more recent update elsewhere. 

 

But if these tables have specific audio code I wonder if I overwrote a file  w a new table (some downloads come w a few extra files / dll files that were more recent versions. I had music and sound on these tables until a month have not done a full update -  so I may just go back slowly and check some things.

I can't think of anything that would affect audio on those tables other than VPM, but maybe there's something I'm not thinking of.  Some tables have separate sound sample files as a workaround for audio emulation problems, but as far as I know all of the DCS tables just use the VPM emulator.  If you did have versions with separate audio sample files, that could be the problem.  You might try just installing the latest versions of the table .vpt files and ROMs from vpforums to see if that helps.  (The current version of STTNG that's on vpforums is a really good implementation, by the way, so if you do have an older version you might want to grab the current one just for the quality of the table.)

Thanks again mrj and BobAlbright.   Based on what you said about the sound and code I went over my PinMame folder figuring I must have overwritten something. Sure enough - I had updated a dll file from  2015 that came with a specific table.   When I reloaded the dll file from 2009 I got voices and music back on all 3 tables! 

(at least I kept a backup of the specific dll file  - but I couldn't remember doing this).  Not sure what this will do to other tables - we'll see.

After what I thought that I had solved this problem, I tried Judge Dredd the other night and again... No sound. I'm using the Sam dll so that I can play the Stern tables...wonder if that could be the problem!?
