Description Christopher Tubbs 2008-05-01 23:46:29 UTC
+++ This bug was initially created as a clone of Bug #444388 +++

Description of problem:

Sounds lag while playing armacycles-ad/armagetron-ad. All possible variations of
quality / buffer size / sound sources tried, with no significant improvement.
(Low quality lags the least, but sounds horrific).
For example, certain sound effects, such as turning, don't play right away, and
appear to be buffered one after another, so that shortly into the game, this
"sound lag" for the turning quickly becomes a sort of constant, repetitive,
ticking sound. Even if only two people turn at the same time, it sounds like a
"tick-tick" one after another.
This issue did NOT occur in Fedora 7, but I have noticed the problem in Fedora 8
(i386 AND x86_64), and Fedora 9 (Pre-release, i386), so I'm pretty sure it's a
PulseAudio related bug.

Version-Release number of selected component (if applicable):


output of rpm -qa | grep SDL (in case it's relevant)

output of rpm -qa | grep pulseaudio (in case it's relevant)

How reproducible:

Steps to Reproduce:
1. Install armacycles-ad into "clean" Fedora 8 or 9 install (currently confirmed
with Fedora 9 pre-release, haven't tried Fedora 8 recently)
2. Play multi-player Internet game (most noticeable in multi-player Internet
game, but still tiny bit of delay with sounds in single player local game).
3. Turn and listen to sound effects.
Actual results:
Sound effects seem to be buffered (queued) and played one after another,
resulting in a constant repetitive ticking.

Expected results:
Sound effects should play right away when turning, and not delayed until a
previous effect has completed.

Symptoms seem to be similar to BZ 441063 that I entered on 5 April. I had
noticed that, even when testing the sample sounds for the GNOME desktop (and KDE
desktop) event sound effects, I had to wait for one clip to finish playing then
wait a few seconds for the ensuing low-level hiss to cease, before playing the
next clip.

Changing version to '9' as part of upcoming Fedora 9 GA.
