Hi all First of all, I am new to kernel programming and an other attempt already failed to do so. However I got familiar with the Intel HDA Codec specification. So I did a start script to log dmesg and mixer controls of different configurations. But I am not sure if I got a functional kernel driver setup to test things. It seems there is something wrong. The codec has 8 GPIOs and first I didn't set any mask within the kernel. Now, I just compile a kernel set it to 0xff. Any help is appreciated. Finally here is my work: https://github.com/joelkraehemann/hda-tool/ Note: I have tried to subscribe using a different email address but didn't get approved message.
