Sorry if this is a stupid thread but I am really struggling to control showtime volume level. Increasing or decreasing the volume level does not have any control over audio loudness. Showtime can only control audio by muting or unmuting. Right now I am using debian squeeze with alsa 1.23 with Sound output via spdif cable from the nvidia 9400 gt card to the motherboard. I dont know what further information I should post. Please help me.
