And if the many Linux distributions use the same modules you can be sure that there is a race for the newest version of it. My Solaris VM doesnât use ALSA. I tried alsa-lib for OpenSolaris from SFE repository but itâs not needed and thus I removed the library. Andreas

FWIW under (Open)Solaris sound isnât working either.
