COMI: no sound with ALSA

Game: Monkey Island 3

Description

Hi all,

after startig monkey3 with scummvm-0.7.1 I can't hear any music. I tried with "default" and "ALSA" setting (I use ALSA on linux 2.6).

I do not hear any music or speech. Some ideas?

Summary: no sound with ALSACOMI: no sound with ALSA

comment:2 by eriktorbjorn, 15 years ago

I assume you're playing the game from hard disk. Did you copy the files in the "resource" directories from your CDs? In particular the files musdisk1.bun and musdisk2.bun since they're the ones that contain all of the music.

comment:3 by (none), 15 years ago

Yes I copied all files from both CDs under RESSOURCES to disk as well. Maybe scummvm can't find those, because files are case senstivie under Linux?

Is there some kind of debugging mode, to see which files scummvm wants to load?

Greetings, Mathias

comment:4 by eriktorbjorn, 15 years ago

In that case, try renaming all the files to either all upper-case or all lower-case letters. ScummVM ought to be able to find them then, at least.

What is the status of this item?

comment:7 by (none), 15 years ago

Status still the same -- I renamed all unter "resource" to upper or lower case. When every file is in upper case, scummvm says "can't open file ..." -- so it seems, files have to be lower case.

But even then I can't hear any sound or music. Seems like my sound system is not used (I use ALSA and KDE). Sound system works, I can hear music via xmms or KDE tools w/o a problem. I even tried to start scummvm, with "artsdsp".

When starting scummvm via cmdline I get this output:

unix_connect: can't connect to server (unix:/tmp/mcop-root/itchy_lame_at-70e3-428f8da8) Unable to connect to UNIX socket /tmp/.esd/socket Looking for comi Trying to start game 'The Curse of Monkey Island' WARNING: Sound mixer initialization failed!

Actually, the "ALSA" setting in the GUi is fr MIDI only. But COMI doesn't use MIDI, it uses digital output, and that is simply passed on to SDL.

Which audio system SDL uses is not influenced by ScummVM at all. In your case it looks as if it tries to use ESD but that fails for some reason. But you can use the SDL_AUDIODRIVER environment variable to tell SDL to use another default audio driver. See <http://sdldoc.csn.ul.ie/sdlenvvars.php>

comment:10 by (none), 15 years ago

Thanks for your info about SDL and audio, but I can't get it to work with the SDL_AUDIODRIVER env. var. either :(

I tried with these calls on cmdline: SDL_AUDIODRIVER="artsc" scummvm SDL_AUDIODRIVER="alsa" scummvm SDL_AUDIODRIVER="alsa" AUDIODEV="/dev/dsp" scummvm SDL_AUDIODRIVER="alsa" AUDIODEV="/dev/dsp" artsdsp scummvm SDL_AUDIODRIVER="artsc" scummvm

none of them worked :( What do I wrong?

comment:11 by fingolfin, 15 years ago

Do other programs which use SDL produce sound output?

Did you make sure the volume settings are not set to 0 (look at the builtin options dialog) ?

comment:12 by (none), 15 years ago

I don't think other SDL based programs do have problems with sound -- for example, I can hear sound when I play Never Winter Nights.

And I checked builtin optons dialog -- volume settings are at maximum...

comment:13 by fingolfin, 15 years ago

NWN ships with its own copy of SDL, so that doesn't say much.

So, do you get the "/tmp/.esd/socket" message even when setting SDL_AUDIODRIVER to alsa ? Or what message(s) do you get?

comment:15 by eriktorbjorn, 15 years ago

The "Sound mixer initialization failed" message means that _mixer->isReady() returned false.

The isReady() function returns the value that was returned by _syst->setSoundCallback() when the ScummVM mixer class was initialized.

With the SDL backend, the only case where setSoundCallback() returns false is if SDL_OpenAudio() fails. This, of course, is where the whole thing passes out of ScummVM's hands and into SDL's.

I've added a warning message to this case that includes whatever error string SDL provides. Of course, that won't make any difference to whether or not it'll work.

comment:16 by fingolfin, 15 years ago

So, we need the bug submitter to try with a current daily build, and then we need to know what additional output ScummVM now produces...

ok, so I downloaded latest scummvm (20050626) and compiled it. But when I now try to start the gane "COMI", I get this error on cmdline:

[ 14:57 haim@itchy scummvm ] ./scummvm Looking for comi Trying to start game 'The Curse of Monkey Island' Fatal signal: Segmentation Fault (SDL Parachute Deployed

comment:20 by eriktorbjorn, 15 years ago

Hmph. Not really an improvement, though I don't think my change would cause that.

Could you run ScummVM in a debugger to see where it crashes?

comment:21 by fingolfin, 15 years ago

haimat, is that really precisely the content of your console?

If you just enter "./scummvm", it will not launch comi normally, so I have the suspicion you are leaving out bits here... ?

comment:22 by (none), 15 years ago

hi fingolfin, yes that's precisely the content of my console, I c&p it from there. To be 100% accurate: - downloaded latest CVS source - "./configure" and "make" - run "./scummvm" from this directory - select COMI game from within the scummvm GUI

After that, the GUI exits and I can see this error on cmdline:

[ 14:57 haim@itchy scummvm ] ./scummvm Looking for comi Trying to start game 'The Curse of Monkey Island' Fatal signal: Segmentation Fault (SDL Parachute Deployed

@eriktorbjorn: maybe this error now occurs because I configured and maked the sources from cmdline? The "official" build 7.1 was made via emerge on my Genoo box from portage ebuild...

comment:23 by eriktorbjorn, 15 years ago

Shouldn't make any difference, I believe. If it had been the other way around, I might have been more suspicious because I hear Gentoo can be pretty aggressive about turning on optimizations which could expose previously unseen bugs both in ScummVM and in GCC itself.

As I said, it'd be really helpful if you would try running ScummVM in a debugger. If you have GDB installed, it's quite simple: Instead of starting it with "./scummvm" you'd start it with "gdb ./scummvm".

After a brief copyright notice, you'd see a "(gdb)" prompt. Type "run" to start the program and if/when it crashes, type "bt" at the prompt to get a backtrace. The output from that should show where the crash occured. (At least if ScummVM was compiled with debugging symbols, which it should be in this case, and hasn't been stripped.)

comment:25 by eriktorbjorn, 15 years ago

That looks quite similar to the backtrace in http://www.libsdl.org/pipermail/sdl/2004-June/062716.html but I haven't found any followups to that yet.

comment:26 by eriktorbjorn, 15 years ago

I couldn't find any followups, but since it appears to be aRts that is doing the crashing, and not ScummVM or SDL, it might be worth trying not to use aRts. I don't know enough about it to say exactly how, though. (My sound card already allows several applications to use it at the same time, so it doesn't need any sound daemon to act as mixer.)

There's an "aRts Troubleshooting" page at http://wiki.kde.org/tiki-index.php?page=aRts+Troubleshooting but I don't know if it's at all helpful.

comment:27 by fingolfin, 15 years ago

This looks as if your version of SDL was linked to audio libs which were then changed in a binary incompatible fashion... Can you recompile SDL, or install a different version of it?

comment:28 by (none), 15 years ago

yeah fingolfin, thanks a lot, that was it! After re-installing SDL I now can hear sound and music in COMI

This solution fixes this bug. Greetings, Matthias
