ALL: Sound is out of sync

Reported by: SF/noltec Owned by: fingolfin
Priority: normal Component: Audio
Version: Keywords:
Cc: Game:


Voice output and SFX is out of sync. The sound comes a half of a second to early. This is true for cut-scenes and during the game. Is it somehow possible to change the sound-sync of the game?

Originally I have only tested it with COMI. The same issue occurs with other games as well:

- Day Of The Tentacle (German - talkie) - Indiana Jones Fate of Atlantis (English - talkie) - Sam and Max (English - talkie)

The sound-output (Music and SFX) comes about a second to early and is not "lip-sync" with the actors talking.

please don't mess with our tracker item priorites, they are for internal use only. We decide what we deem important and what not...

Anyway: I can't reproduce the problem here (on an Mac OS X machine) at all, with none of the games you mention. It may simply be a problem with your local sound setup.

It's strange that he gets the sound too early, though. I've heard people complaining about the sound coming too late - usually as a result of some sound daemon holding things up - but too early... that's a first.

Sorry for messing with the tracker, I did not intend to confuse anybody...

I have to apologize for another thing: the sound does *not* come to early, as stated by me, it comes too late. (sorry about that!) I will check my sound-configuration further.

Some details of my configuration: ALSA ver. 1.0.6 (I will try it with 1.0.7 soon) SoundBlaster Audigy Player (emu10k)

What I have already noticed was the software-emulation of the midi-sound (adlib) which scummvm did because of a missing synth device. I have fixed this. Midi-synth is now done in Hardware. This improved the synchronicity with the midi-based sfx. Speech still is out of sync (it comes too late). I'll check that later!

The sollution is as follows:

I am using KDE 3.3.1 an disabling the artsd solves this issue. Does anyone know how to configure the artsd correctly? I have tried every setting with no effect. The only thing I can do is to disable it completely. Could this be a bug in artsd? All other sound-apps work fine without a problem (with artsd enabled).

Thanks for the feedback, noltec.

Problems with artsd, that's a problem we've encountered before. As I understand it, the problem is that artsd simply has a relatively high latency (being a sound server process, and such); in most programs (like a MP3 player) you simply don't notice this because you have no graphic reference to compare to. As such, it's probably not a "bug" in artsd, but more a design problem.

For a mp3-player this would be true, but I use mplayer to play my video files (also through alsa) and there are no such issues with video/sound sync. Could it be that the mplayer goes directly on the alsa library with bypassing artsd? If so, would it be possible to implement the alsa-sound layer in scummvm so that it bypasses an enabled sound-server (artsd, esd,...)?
