It should say something like "Playing id1/music/track001.mp3" or "Track id1/music/track01.mp3" not found.

Which does it say? If it says "Playing ..." and it isn't working, check both the music volume slider and the volume slider. If it still isn't playing, then I don't know --- Fifth had some issue like that and then he did something and it worked. 

It should say something like "Playing id1/music/track001.mp3" or "Track id1/music/track01.mp3" not found.

That's the problem. I searched for my problem through this thread and everyone mentioned that it should had been a warning about that. While I don't get any warnings at all. Is there any console command to switch on/off music or anything else I have missed? External music is enabled in options, sound and music volume sliders don't make any changes.
I'm confused. 

Music has worked for me since one of the newer builds. I just assumed that you had figured out the issue and fixed it... directory structure and file naming is
..\Quake\id1\music\track02.mp3 

1. I created a new folder "Quake"
2. I created a Quake\id1 folder
3. and copied pak0.pak and pak1.pak in there.
4. I created a Quake\id1\music
5. Copied an mp3 as Quake\id1\track04.mp3

Using this latest Mark V beta for Windows (download)

I have no config and there is no command line. I start Mark V and do single player new game so I am on the Introduction and it says

"Introduction
Using protocol 666
Current music track: music/track04.mp3"

And the music plays.

So no config, no command line, current .exe that's what it says with a valid mp3 in Quake\id1\music\track04.mp3 on the "start" map. For me. 

correction ---> quake\id1\music\track04.mp3

(I typed it wrong the first time) 

I repeated all these steps with new quake folder etc (btw I've discovered that I've been using previous build (from 20150426) while having the latest one downloaded).

After all I got:

"Introduction
Using protocol 666"

And no music.

That's with clean quake and the latest mark v. 

Are you using a command line that has something like -nocd or -nocdaudio or -nosound or something?

It either prints that ...
A) it found the track
B) it didn't find the track

It seems you have the music disabled somehow. 

 

It doesn't say something like "ERROR - Could not initialize COM library" if you scroll up in the console does it? (Seems unlikely)

Also: Type "developer 1" in the console and then type "map start" and it will print out "too much detail" but might give you a clue and will print music messages like if it found the file.

About all I can say. 

and the tracks play just fine in quakespasm. In mark v, the message about "current music track" displays for me as well, but no mp3 is playing. 

To anyone who's interested here's the controller configuration I use.

Just copy the text below and paste it into a new text file. Save it as "controller.cfg".

Then just add the line: "exec controller.cfg" to your autoexec.cfg in your "Quake\id1" folder.

Copy text from here:

To the line above!

PS: I realise most of you will know what to do with the above text. I just thought it prudent to add some simple instructions for those not familiar with such things. :) 

The game loads fine but crashes every time I pick up and shoot the incendiary grenade launcher at the Death Knight as found in the first secret area in the first map.

I'm using the latest build from above (20150508) on Windows 7 Pro 64 bit. 

Mark V uses DirectShow to play MP3 using hardware acceleration. Because DirectShow is part of Windows, there are buried settings in the control panel audio settings or even sometimes Windows Media Player (volume per file type) that might affect it.

Your Abyss of Pandemonium issue might be related to Shrak invalid skin bug. Whenever in the future I do an update to Mark V I'll take a look at it. 

Given that it's DirectShow, it might be worth running that DirectX Web installer (from Microsoft.. don't have a link handy.)

A while ago, I was getting a missing d3dx DLL error when running DirectQ on a fresh Windows 10 install, and running that web installer fixed it. 

I tried AoP with the OGL version of Mark V and it works fine. It only happens in the WinQuake build.

I tried Erics suggestion in the hope that it was indeed just a glitch in the matrix but the issue's still there.

Anyway, just thought I'd let you know. :) 

In developer 1 mode I get this (map start):

"Introduction
Using protocol 666
CDaudio: Bad track number 4"

I get a feeling that it doesn't even try to find mp3s.

I've inserted an audio cd and checked. With external music off I get no "CDaudio: Bad track number n" warning but cd music doesn't play either. Though that cd plays well in windows media player.

I need to investigate in on my pc at work. 

Since I've very much enjoyed some of your past maps like Menk, I tried to think of some solutions outside the box.

But the problem you are having is "outlier".

(i.e. the particulars of the problem you are having don't match anything anyone else has had in a thread over 3 years old.)

So I don't know and I can't think of any helpful advice. 

Well, hold on ----

In Mark V, a CD track > mp3

It assumes if you have a CD in the player, you intend to use it.

CD supercedes MP3.

Answer: Don't have a CD in. 

That makes sense. I think the cause of the problem is that I have a virtual drive, that has a letter prior to the physical cd drive. So Mark V thinks that I always have a cd in my drive.

Music plays fine on my pc on work where I don't have any virtual cds.

Thanks for such investigation. 

Then what does "external music" option do? Description says that you can choose what to play, cd music or mp3, while actually CD always supercedes MP3. 

external_music 1 or 0. Determines if a music track (CD or MP3) will attempt to play. 

The info that the your AOP problem is specific to the software renderer (WinQuake) is helpful information.

WinQuake and GLQuake have different little problems with non-conforming maps, models, textures.

There is some map Madfox made with Q3 skeletons and on the bridge there are some non-conforming textures, for instance, that look ok in Open GL but break the Quake texture spec so bad that in WinQuake they are totally wrong. Nehahra on the 3rd, 4th or 5th map has a BSP with a severe bsp/sky texture irregularity that affects both WinQuake and GLQuake and somehow not DarkPlaces. Probably used what would be considered by Func_Msgboard a very non-compliant map compiler.

Fortunately, these problems are very rare. 

I changed the letter of the virtual drive so that physical cd drive is the first one and mark v started to play music after this.

Thanks for guiding me towards the right direction. 

Sock tries Mark V WinQuake. Mind blown!

"OMG! WinQuake how could I forget you! MarkV Winquake from Baker, #quake pixel heaven!"

Sock, if you read this, I used Zendar and Metal Monstrocity as the primary testing targets for the WinQuake version of Mark V.
