Correct..You've not specified the address the oled should use..
As it is on the default port "3c" it's not necessary to add it with -a 3c (see post #201)
But I also tried this with no luck :-(

I wonder if there is a clash with 2 x i2c devices trying to share the same address....
Can you post the results of this both with the oled attached and without.
pi@moode:~ $ i2cdetect -y 1

As you can see there are only 2 devices on the i2c bus with different addresses.
3c is the display and 4d is the Hifiberry DAC+ Pro
