Asus A8V-MX Mainboard

m_yates · 11-27-2005, 10:31 PM

Has anyone gotten this motherboard to work under Linux? I have been trying for two weeks. It appears that the VT8251 chipset is not recognized, even using the latest kernel 2.6.15-rc2. It prevents DMA from being turned on for the hard disk. As a result, the system is slower than my 5 year old laptop. I was able to install Debian-386, Debian-amd64, Ubuntu-386, and Ubuntu-amd64, but nothing will get DMA working.

I think you are correct. You'd be better querying LKML about this, first via search.

I got it working. Here is a link to the patch needed for kernel 2.6.15-rc2: http://article.gmane.org/gmane.linux.ide/6599 The patch works in Ubuntu (Breezy) AMD64. DMA now works for my IDE hard drive. However, I also tried patching and compiling the kernel in Debian and the new kernel failed with "/dev/hda1 not found". There must be something different with the kernel configuration or boot process between Ubuntu and Debian. I don't have any more time to try and figure out anything else, so I am now a new Ubuntu convert. Everything works except sound.

Sound does not work with this motherboard in Debian (etch/sid), Ubuntu(breezy), or Knoppix(4). I might try another post to see if anyone knows anything about sound. If not, it is off to Compusa for a soundcard

Post your "/sbin/lspci" output for Multimedia Audiocontroller ...

Any help would be appreciated. If I open an audio stream in xmms, it plays sound for about half a second, then freezes. Asus lists the audio chip for this motherboard as "Realtek ALC653", alsamixer shows "Realtek ALC655 rev 1". Here is information on modules:

I am currently using alsa that comes with breezy Ubuntu. I tried upgrading to version 1.0.10 from Debian sid, but that didn't help.

Just curious if sound works at all, or this is a stream problem with XMMS?
Your modules look superlative. I have the same for that VIA soundchip
in a couple of boxen.

Yes, it is a sound problem. If I try playing a video in mplayer, it freezes. However, if I disable the sound in BIOS and restart, the video plays smoothly with no sound. If I try playing "test sound" in kde control center, it freezes. However, it is not a problem with KDE or arts, because I get the same freezing in fluxbox running xmms.

The problem is with the audio driver on Asus A8V-MX which is Realtek ALC653 and is detected al ALC655 rev1. I found a solution to this and posed it on my webpage at http://www.geocities.com/rajahuroman/ .

Thanks for posting the fix. I haven't had a chance to test it yet, but I posted your fix on the bug page: https://bugtrack.alsa-project.org/al...ew.php?id=1622
