If I understand correctly, you mean "PCM" mixer element is not found.OK, that's basically a problem of mplayer. But, in future, we can add"PCM" mixer volume as well. > This won't help > solve the sound-pause problem however. Not sure about this yet. thanks, Takashi_______________________________________________Alsa-devel mailing listAlsa-devel@xxxxxxxxxxxxxxxxxxxx://mailman.alsa-project.org/mailman/listinfo/alsa-devel
