Distro: Debian Squeeze
Kernel version: 3.5.3
Sound card: CS5535 Audio

When I launched Mumble for the very first time, "Audio Tuning Wizard" opened to allow me to configure audio settings. I selected PulseAudio as the Input and Output device and advanced to the "Volume Tuning" screen. When testing the audio in this screen, I either did not hear any output or heard output with significant delay of more than 10 s, often garbled.

When I stopped pulseaudio on the system and chose ALSA in the wizard instead, I did not experience these problems in the wizard and was able to get immediate audio output without any delay.

This ticket has been migrated from sourceforge. It is thus missing some details like original creator etc.

Same issue on Arch (latest version, has been persistent since Mumble 1.2.2 / Arch Iso from June). PA backend lags Mumble and any device on that audio sink, if I use a combined or custom sink for Mumble there is no lag on other output devices on that sink, and using the ALSA backend on top of the PA Alsa compat lib also works.

I'll close this due to age. If this is still a problem, please re-open a new ticket. Thanks!
