FMV choppy sound glitches.

08-06-2012, 12:44 PM #1

System - Mac OS X Lion 10.7.4
Processor: 3.4 GHz Intel Quad-Core i7.
RAM: 12 GB
Graphics AMD Radeon HD 6970M 2048 MB

Having a small problems when any game with an FMV scene appears, choppy sound plays along the video.

At the moment I'm trying to run Tales of Symphony, but I've noticed this for a few other games.

The frame rate is constant 60 and the speed is also constant 100%, so I'm not sure what's causing this.

Dolphin version: 3.0-735

General:
Settings: Enable Dual Core
Enable Idle Skipping.
JIT Recompiler.
Lock Threads to core.

Audio:
DSP LLE recompiler
DSP LLE on Thread

(When set to DSP HLE emulation, still same problem with choppy sound in fmv)

Graphics, General:
Backend: OpenGL
Fullscreen resolution 2560x1440
Stretch to window.

All other settings are left untouched and set on their default.

Try this:

* Set Framelimit to "Audio"
* Change the sample rate from 32.000Hz to 48.000Hz

...Ok let me specify. You have Mac OSX and a mobile radeon, so you are probably on a macbook pro with a mobile CPU. Is this is laptop or a desktop?

This is a known issue with Tales of Symphonia.
Which other games?

Neither
Only an imac would use desktop CPU + Mobile GPU

Fraid this didn't work, 32,000Hz made more sound glitches around the whole game. Framelimit to audio, didn't appear to affect it.

Very noticeably in Fire Emblem GC. Also appears in Baten Kaitos Origins.

Appears to be games with video files. Games that run on graphics are fine, it's just the video cut scenes that aren't playing well with sound.
