oss audio support was enabled by default for <=kvm-70 but is now being explicitally removed because the ebuild is instructing kvm at configure time the list of audio_drv_list generated from the available USE flags. in linux oss can be supported without adding any external dependencies and so will be selected if no driver list is passed, and so alternatives will be : 1) add "oss" by default to the driver list generated 2) remove the audio driver list parameter if the driver list is empty
Good point. Fixed in -r2.
