If you installed it with a differentprefix and it ends up in /usr/loca/lib/alsa-lib then it won't work. Theaudio service needs to be used with the matching plugin. > 2.

The audio service has been improved a lot of 3.26 and thus it mightsimply miss a patch. However for me it is already too old to rememberany details.
