7.5V is maybe too high. Absolute max voltage on any pin is 7V. Even at 5.5V (+/-2.75V), recommended DC max, DS1802 works fine (2.3V RMS input voltage).
In my preamp it works on 6V (+/-3V) without any clipping problem with standard CD/DVD component line out.

At power up, volume is min, not mute. Problem?

Don't be so sure! It works with microcontroller nice, too.
