Description

Game Name?
Super Smash Bros. Melee

Game ID?
GALE01

What's the problem? Describe what went wrong in few words.
Loading a save state causes a pulse underflow which increases latency, however, because it is triggered every state load instead of during normal play it is possible to increase latency until the audio becomes a crackling mess and is delayed by more than a second.

What did you expect to happen instead?
I would expect state loads to not raise latency, at least not infinitely.

What steps will reproduce the problem?

  1. Set the audio backend to pulse
  2. Open a game and create a save state
  3. Load state and check the output log - should say 'pulse audio underflow, new latency: xxxx bytes'
  4. Load state about 20 times for bad audio

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
2050

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Arch Linux 3.16.6-3-ck
CPU: 3570k
GPU: Nvidia 560ti
Pulseaudio: 5.0

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
