No Music in Linux

Conditional Zenith · Post by **Conditional Zenith** » 16 May 2004 05:39

I am running OTTD in linux, but cannot get music. I have copied the gm folder frow Win TTD into both the OTTD directory and the OTTD/data directory, but I cannot get music. I can get sounds fine. Does anyone know how I can get the music?

Also, while it is not affecting me while I am playing, I am getting many "dbg:frameskip" (or something like that) messages in my terminal which I find after I have quit.

don't care about frameskips

the gm folder should be in the same folder as the executable file and you need timidity to get it to work. You also needs an addition to timidity, which I always forgets the name of. It's named something like earmuffs or something

I ave the same problem too. I have read the readme, and I tried to put /gm in 5 different places but non worked.

whitehawk do as he wrote ... read is sig ...

after taking brief in 10 seconds I found this:
./ttd -m extmidi
I don't want to give you everything so this is only clue ... search the forum aswell read the readme file to fins it yourself

I also read the readme which came with the source a few times (before I posted here). I got the soure tarball from SF and it had a readme which is 6767 bytes.

All it says about music is:

"If you want music you need to copy the gm/ folder from Windows TTD."

It says nothing about any -m option.

yes there is:

Readme Mandrake Linux.txt wrote:If you want the original TTD music you need to copy the whole /gm/ directory from Windows. Additionally the TiMidity driver is required:
TiMidity++-2.12.0-0.pre1.4mdk (+ dependencies)
To run OpenTTD with music support type
$ ./ttd -m extmidi

The text you just quoted was definitely not in the readme I got with the source. I did not get any file called "Mandrake Linux.txt" either, only "readme.txt".

Somebody told:

which tells:

"There's a readme that comes with the source. I suggest you read it."

There you could find the readme file which is released at May 8th and OpenTTD 0.3.1 is released at April 26th.
I hope that in the next release this readme is included.

Ive done as the readme states and if i run

Code: Select all

timidity somettdmusicfile.gm

i get the music playing, but if i run

Code: Select all

./ttd -m extmidi

i still don't get any midi, and i have all the files
from /gm/ lying under /gm/ in my gamefolder on linux.

Can anyone plz help me to what i am doing wrong?

Are you sure that you have them all in the correct folder? Look at Makefile.config and check "DATA_DIR_PREFIX:=". Is it set to any particular directory? If yes, you have to move the gm folder to the specified directory.

Gof.dk · Post by **Gof.dk** » 03 Jun 2004 13:22

Ok thx a lot i thought it had to lie under the openttd folder as /gm/ and not data/gm/

Gof.dk · Post by **Gof.dk** » 04 Jun 2004 16:29

Ok i tried moving the gm folder and i found out that that wasen't the problem
because when i moved it i got file not found errors while playing openttd,
so the location was right, i moved em back and errors dissapeared.
But i still get no music.

I know timidity++ is working because i can play the songs with timidity,
and i know the .gm files is in right location because if i move them to
somewhere diffrent i get file not found errors. And i am using ./ttd -m extmidi
to start the game. But no music

Anyone have any good ideas?

I have exactly the same problem.
I traced it into that OTTD has already taken my soundcard for sound effects. Timidity then waits until it's freed, which is never while playing.

SuspiciouS · Post by **SuspiciouS** » 10 Jun 2004 18:22

Well, i tried all the things that are listed in the readme... But no sounds here.

In Makefile.config i set DATA_DIR_PREFIX:=/home/dennis/games/openttd

But then also it doesn't work, i get this error:

Code: Select all

extmidi: couldn't execl: No such file or directory
extmidi: play song failed

Runnig RedHat 9, installed the latest TiMidity++, rebuild the game, nothing helped.

Anyone who had an idea ?

voyageur · Post by **voyageur** » 12 Jun 2004 12:12

I have the same problem as Nikerabbit, because my crappy sound card can not do multiplexing... So timidity won't be able to play, because sound is already in use by the game itself

I think this was already suggested, but why not use SDL_mixer instead of fork+execl of timidity? Since SDL is already used for sound... Sadly I don't have time to check it out myself, but combining existing code and some inspiration from SDL tutorials (like http://www.kekkai.org/roger/sdl/mixer/index.html ) could make it.

Bjarni · Post by **Bjarni** » 12 Jun 2004 13:11

there have been talk about SDL_mixer, but nobody have started to code that

It would solve this problem and the problem that some people haven't installed timidity and the problem where the mac port uses too much CPU time

I have the same problem as you and apparently, it doesn't come from the game but the multiplexing drivers as voyageur stated :

I tried launching the game by :

./ttd -s null -m extmidi

then the music worked but evidently without sound
I remember that I can't play - let's say - mplayer and xmms together so it must come from the mixer or something. Does anyone knows how to solve that ?

voyageur · Post by **voyageur** » 25 Jun 2004 17:20

A fix is to use a software multiplexer, namely esd, arts (from kde), jack, or dmix (if you have alsa sound drivers). But you have to set them up to intercept sound, and using programs like esddsp to do so (in this case extmidi.c calls have to be modified to use it).

But I recently discovered that the alsa drivers/libs have a software multiplexer, timidity can use alsa and sdl programs too. I'm currently trying to make all of these work on my system (side effect: allow xmms to play ogg files and licq to play "new message" sounds)

See:
http://alsa.opensrc.org/index.php?page=DmixPlugin
http://alsa.opensrc.org/index.php?page= ... irty+HOWTO

Well it's rather a hack than a fix, SDL_mixer would be quite better to it! But using it will mean some recoding of audio output too...
