So i have  to write this post especially for A900 series who have the problem to install audio drivers. So a brief and short intro. This model use Conextant audio drivers, there are many type of conextant audio devices such as conextant smart audio 221, coneextant ac link audio, and conextant venice, so this model tetsed work with conextant venice 5041 driver.

IMPORATNT:
There are overall total of 103 model for A900 model starting with A900 CTO, A900ED .... etc so not all of them use the same conextant driver. Here i will list several driver at the END of this post. So first try with the driver i recommended. If not work repeat the whole installation process using the other driver in the end of the post.
