Cool VL Viewer forum

I recently went back to Linux, Ubuntu 12.10 in particular, and I was having the hardest time finding a sound configuration where the music streams did not lag by 2-3 minutes as configured by the standard Ubuntu PulseAudio and ALSA configuration.

I found something that works.

First make sure ESD is loaded:

sudo apt-get install esound-common libao-common libao4 pulseaudio-esound-compat

Then edit the sound section of cool_vl_viewer like:

## - Avoids using any OpenAL audio driver.
export LL_BAD_OPENAL_DRIVER=x
## - Avoids using any FMOD audio driver.
#export LL_BAD_FMOD_DRIVER=x

## - Avoids using the FMOD ESD audio driver.
# export LL_BAD_FMOD_ESD=x
## - Avoids using the FMOD OSS audio driver.
export LL_BAD_FMOD_OSS=x
## - Avoids using the FMOD ALSA audio driver.
export LL_BAD_FMOD_ALSA=x

You may need to log off Ubuntu (or otherwise restart PulseAudio). Works wonderfully!

I won't recommend using OpenAL... The quality of the sound is poor when compared to FMOD... As for ALSA and PulseAudio, they both suck big time as well !

Try OSS v4 and get rid of all your sound demons (PulseAudio, ESD, Jackit, etc...): with its transparent mixer, OSS makes sound demons useless and prevent any delay in the sound playback.
