From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3 Description of problem: In this game, the sound lags the video by about 5 seconds. (Clicked on "Play Game" then counted "one-hundred-and-one", "one-hundred-and-two"... until I heard the "YU!" sound) I'm using an IBM NetVista with on-board sound and FC3 (fully updated) I have tried artsdsp Maelstrom artsdsp -s -m Maelstrom but the delay is unaffected. Version-Release number of selected component (if applicable): Maelstrom-3.0.6-6 How reproducible: Always Steps to Reproduce: 1. Install latest version of Maelstrom for FC3 2. Start the game from commandline (# Maelstrom) Actual Results: The game displays the title screen, and five seconds later, plays the explosion sound. I click on 'P' to play the game, and again, the appropiate sound effect ("YU!") has a five second delay. Expected Results: Audio and Video should be synchronised Additional info:
Does it only happen when using arts?
No, if I stop arts and run it just with the ALSA driver, it still has the delay. Perhaps this machine (Pentium III (coppermine) 868 MHz, 256 kB cache) is too slow to play games, but I doubt that's the reason.
I also get an audio delay, although it's for me it's closer to .5-1 seconds. In addition, after extended play (an hour), I get weird audio artifacts. When asteroids explode, it sounds like the speakers are blown (but they're fine). The artifacts go away if I restart the game, but the delay remains. Maelstrom-3.0.6-8 on FC4, Pentium 4 2.4Ghz w/ 512MB RAM.
FC3 and FC4 have now been EOL'd. Please check the ticket against a current Fedora release, and either adjust the release number, or close it if appropriate. Thanks. Your friendly BZ janitor :-)
I've tested this on FC-6 and the devel tree - I can't reproduce it. Please reopen if this occurs on a current release.
