I got a new soundcard - Asus Xonar DX - and when SL uses openAL I get really bad sound with crackles. If I let SL use Alsa I get great sound but only SL can play sound - it grabs my device.

Any ideas? I really want to be able to have SL and other apps using sound at the same time, but I sure don't want crackly annoying sound.

I installed esd and that made it work, now I just have a long delay in what I see in SL and what I hear. At least I have sound.

It would help to know what distro you are using.

You can disable OpenAL from the secondlife script. Edit it and make sure to un-comment the LL_BAD_OPENAL_DRIVER export, like this:

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

I too have problems with OpenAL (some UI sounds do not play, and the sound quality is much lower than with FMOD), so better sticking with FMOD for now...

Also, consider switching your sound driver to OSS v4.1 (http://www.opensound.com/oss.html) which got a transparent mixer and will allow you to get rid of all the silly sound wrappers/daemons such as esd, pulse audio, jackit, arts, etc... This however supposes that ALSA was compiled as modules only (this is usually the case) and that your distro provides support for OSS (for example, with Mandriva 2009.0, I had to rebuild a couple of packages to enable support for OSS in them. Namely: portaudio and mpg123).

I deleted libstdc++ (or something resembling that) from the sl lib folder, after seeing that gstreamer threw some errors about that. That solved my crackly audio problem...

That is on a kubuntu 8.11...., with "plain" alsa
