I have installed Ubuntu 12.04 on an old Aopen AX4B-533 Tube Motherboard (P4 2,6ghz - chipset Intel 845E - sound chip RealTek ALC650 AC97 ) and I didn't find out any solution to make the audio system working. The audio system is tube boult-in audio system (is the main reason why I have decided to buy this MoBo). Did anyone have experience with same MoBo? Is there any suggested solution (packs to be installed,...)?
Thank you in advance.
