The Xonar D2 has not volume control on its input; it assumes that the input signal has line level, and that you can control the playback volumn with its playback controls. The HDMI output does not have a volume control because it assumes that the destination device already has one. PulseAudio appears to have a loopback volume control: http://askubuntu.com/q/440562/90892 Regards, Clemens ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
