Problem: DE1-SoC Audio Codec

Hello everyone. I'll start by saying that my english sure it's not the best, i apologise for that; but i'll try anyway to be as clear as possibile. I'm trying to realise a project on my DE1-SoC...

Oh yes, I have the virtual base set up and it successfully maps.

Also when reading back the GPIO48(see following instruction), I do see that it's cleared.

hps_gpio = alt_read_word(( virtual_base + ( ( uint32_t )( ALT_GPIO1_SWPORTA_DR_ADDR ) & ( uint32_t )( HW_REGS_MASK ) ) ));

However, the LED I've assigned to it does not deactivate.

I'm wondering if you were using Altera University's audio core to interface with the mic. It may be that a few settings on my HPS are not correctly setup.
