Mumble heavy lag

[Meow]

I had no problem with mumble with 0.98 on my laptop but 1.0 is pretty much unplayable due to the mumble lag.
(system info below)

- Other players' voices are very laggy and stretched out to the point that it is impossible to tell what they are saying.
- There is a laggy static noise in the background.
- The frame rate on certain maps works fine but on others is so low that is unplayable.
- Sometimes the game starts running normally when there are no players around me but the issues begin again as soon as i get near other players. Other times the lag starts as soon as I spawn the first time on the map.

I have turned down all my video settings and set audio quality to low in both software and hardware options. I have tried different configurations for the quality, audio packet, noise suppression, jitter buffer and output delay.
None has made any difference.

When i installed PR I had Microsoft Security Essentials on but after reading old threads I turned it off but the problems continued.

Is it possible that the previous version of mumble did not uninstall properly and is messing with the 1.0 integrated one?
Would uninstalling and cleaning out the registry files solve this issue?

Did you lower the audio quality in PRMumble itself?

start PR, alt-tab, in system tray, open PRMumble,

in Configure->Settings->Audio Input
Lower the Compression-> quality setting.

in Configure->Settings->Audio Output
Increase Default Jitter Buffer, It has been reported that 30 ms is the best place to start, then test and adjust.

Common Issues

Audio
Advanced Config
If the sound overdistorts or you hear high-pitched frequency pops, try getting whoever you hear having that problem to turn down their Amplification at Configure -> Settings -> Audio Input, turn off their Mic Boost, and/or turn off Automatic Gain Control (AGC), or a combination of all three.
If you are experiencing audio anomalies or glitches (robotic noise, audio cutouts, etc), many times, setting your Default Jitter Buffer and/or Output Delay to a higher value will fix it. Try playing around with the two settings. You can find them at Configure -> Settings -> Audio Output. It has been reported that 30 ms for Jitter Buffer and 30 ms for Output Delay works well for many people who experience these types of problems.
If the problems still persist, go to Configure -> Settings -> Audio Input and set everyone's Compression such that it shows "Speex" in the black text underneath the Compression box. Any setting that is <= 32.0kbit/s @ > 20ms audio per packet will be Speex.
If the problems persist, try setting your bandwidth lower at Configure -> Settings -> Audio Input -> Compression box.
