Expanding, with the 'Line' control at 0 dB (74 integer) and 'Analog Mix' at 0 dB (100 integer) everything does sound right with both 'Master Capture' and 'Master' at full, and too faint with 'Master' at -16 dB. I guess this indicates that it's something at the DSP side only? (sort of loosing my way in this bewildering array of controls so if I need to be guided to possibly say sensible things -- please do) Rene. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
