Got sound but no music under linux, ubuntu

[Tuffy]

I can only hear the sounds while in game, not the music. Ive copied all the .gm files from the original game to the necessary folders, and while in game, when I press the jukebox button, it speeds through all the songs. Like when you have the song files, but they are empty. However, I already checked this and the files have (I think) the correct sizes.

Im running Ubuntu Edgy Eft, with a USB headset.

thanks for any help,

Hi Tuffy,

I have experienced the same problem, but I know that my sound card does not play midi files in linux/alsa. At least so far I could not set it up with my SB Audigy LS. Can you play other midi files?

Do you have timidity or some other midi player on your system? You either need to specify it yourself, or compile it into openttd.

You might find this useful. You need to set ubuntu up to be able to play midi.

Thanks Darkvater and phil88. Based on your instructions, I have installed timidity and the midi files are being played well in the game.

I have managed to get openTTD to play music using my SB Live's wavetable. This way it's not using timidity and caning my CPU.

I'm running Ubuntu Feisty (7.04), so adjust as necessary for your distro.

First install the awesfx package.
Then find the files 8mbgmsfx.sf2 4gmgsmt.sf2 and 2gmgsmt.sf2 from the SB Live installation CD (or somewhere on your windows partition) and put them into /usr/share/sounds/sf2

Run

Code: Select all

asfxload 8mbgmsfx

to load the soundfont into the sound card.

Next run

Code: Select all

aplaymidi -l

You should see output something like this:

Code: Select all

 Port    Client name                      Port name
 14:0    Midi Through                     Midi Through Port-0
 16:0    SBLive 5.1 [SB0060]              EMU10K1 MPU-401 (UART)
 17:0    Emu10k1 WaveTable                Emu10k1 Port 0
 17:1    Emu10k1 WaveTable                Emu10k1 Port 1
 17:2    Emu10k1 WaveTable                Emu10k1 Port 2
 17:3    Emu10k1 WaveTable                Emu10k1 Port 3

Note the port for Emu10k1 Port 0 (17:0 in this case)

run the following substituting for the port above.

Code: Select all

export ALSA_OUTPUT_PORTS="17:0"

you should now be able to use aplaymidi to play one of the gm files from the gm directory.

Assuming That worked correctly, the last step is to edit ~/.openttd/openttd.cfg

In the [music] section set the extmidi line to:

Code: Select all

extmidi = /usr/bin/aplaymidi

You should now have midi sound woring in openttd without it eating up all your CPU time.

good luck,
Alex

Would you mind adding this in the wiki? (at the right place of course). Would be very useful! Tnx

[Sacro]

Indeed, I shall be trying it later (I only just realised my soundcard supports it!)

No problem. See here.

I've put it in the Installation Category, but I haven't linked to it from anywhere yet. I'm still finding my way round the wiki. Suggestions/improvements welcome.

thanks,
Alex
