Me, too. ASUS A8V-MX board, AMD64 CPU, FC3-i386 system
tried FC4 base kernel 2.6.11-1.1369_FC4 (hda DMA fails)
FC updated 2.6.15-1.1871_FC5
kernel.org 2.6.16-rc1

lspci shows VT8233/A/8235/8237 AC97 Audio Controller (rev 70)
  Class 0401: 1106:3059 (rev 70)
Sound is OK for about a second then stops.
With dxs_support=5 sound is OK for about 4 seconds playing 11025/sec file

Tried pci=noacpi, index=0,  id="VIA - no difference
Tried looking for drivers at asus.com and viarena.com. ASUS has
current ALSA driver (lists VT8233 up to rev 60, I have rev 70).
VIA has mostly old stuff (2.4 kernel, RehHat8/9) which I could not build
even though it says "FC4". Hard to find things on their site; their
driver directory is not browsable and some links are broken.

Have submitted this issue to ASUS
http://vip.asus.com/eservice/techmailstatus.aspx?ID=WTM2006012863983987
Looks like a boilerplate reply - talks about Windows though
I checked "Linux".Some suggestions re. rearranging IRQ.

Bootup syslog includes
pcie_portdrv_probe->Dev[287c:1106] has invalid IRQ. Check vendor BIOS
Hmm.. think that may be  VT8251 PCI bridge (match with "lspci -n")

I have attached mplayer8251.strace, which is from a custom 2.6.15 kernel on
Debian. The problem exists on other 2.6.15-kernels tested, as well as on a
box running Mandriva 2006.

Other media players fail in similar ways, either crashing or going into an
endless loop.
