The card won't work on other boards since it's just a riser card, part of the hardware stuff is located on the mobo while the sound chip is on the riser card. It's exclusive to some Asus x48 Maximus/Rampage boards with the *dedicated* black PCIe x1 slot for Supreme FXII Card. It will never work on the regular white slot on any other board.
The linux sound stuff/stack can't apparently recognize whether the setup is a 5.1 or 7.1, on Windows the Asus SoundMAX AudioESP sound software automatically reconfigures the sound settings depending on what has been plugged. Whenever connector is inserted/removed it will prompt to select another configuration. http://img.techpowerup.org/090513/soundmax.png http://img.informer.com/screenshots/0/312_2.gif http://lh3.ggpht.com/renjusgallery/Ryt9PP8zTJI/AAAAAAAAAec/RcQ17Q-_K_Y/s800/soundmax%5B5%5D.jpg My problem is that Linux thinks that I'm using 7.1 and outputs sound in via 4 speakers while ignoring the subwoofer, it ironically shows the 5.1 config enabled in sound settings but I have to constantly switch from 5.1>7.1>5.1 to get the subwoofer working every time something is being played(And it doesn't always work). Let's say I play an MP3, the default setup is 5.1 and I have to mess up with the settings to get it working but whenever the App playing the content is closed Ubuntu forgets the subwoofer so I have to do this every single time. The sound quality is also terrible, it's way too quiet and the bass level is abnormally too distorted compared to what SoundMAX on Windows. There's a sound switch that needs to be done but Ubuntu can't apparently do that. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1120853 Title: [AD1988B,] 5.1 surround sound unresposive or of poor quality Status in “alsa-driver” package in Ubuntu: In Progress Bug description: Card info is as follows... card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 3/3 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I tried to look after the problem with the following ubuntu fourum post: http://ubuntuforums.org/showthread.php?t=2103358 any more suggestions would be much appreciated.
