Hi, crew. I use HDSP 9632 for a long time. Recently I began to pay attention that the stereo sound became not super voluminous.
This problem is solved by quickly switching "Snapshots" to Totalmix for a short time [3-9 sec. sound perfect and deeper]. Later, the sound becomes again not very attractive and voluminous. If you press the "Store" button in Totalmix  - the sound is voluminous but floats, I hear it in the monitor headphones. I replaced the capacitors 4x22OmF [I'am radio engineer by education] and 2x47mF - their factory performance was below normal from exploitation. I changed the factory Nippons. Now the problem has not changed, although I have 4x Elna Silmic 2 / 2x Nichicon KZ Muse. In general, the sound is excellent on warm Silmic 2 but it's not as big as it used to be. Maybe the problem is in the DSP - the card is very old and has never let me down. I'm using Win7 SP2 and pretty new drivers - everything works stably. I want to understand the reason where the old quality disappeared. Thanks
