I do not have any 64bit setup, are you sure that your 64bit patch is
correct ?

http://kerneltrap.org/node/3848

snd-au88x0 use the following macros to perform read/write of 32bit data
from/to Memory Mapped I/O

#define	hwread(x,y) readl((x)+((y)>>2))
#define	hwwrite(x,y,z) writel((z),(x)+((y)>>2))

Would you provide the result of "lspci -vvvn" to find out the content of
PCI BAR0 of your au8810 card ?

What is the model of your au8810 card (e.g. Vortex Advantage, SQ1500,
SoundCom V90) ?

Do your 64bit machine has more than 4Gb memory ?

Do your configure all the sound-apps to use ALSA instead of OSS ?

This is abnormal, au8810 has 16 SRC and snd-au8810 can play either 16
mono streams or 8 stereo streams concurrently.

Use alsamixer to find out which ac97 codec on your au8810.

Do you have any application using gameport, mpu401 or OSS  ?

Do the log indicate the snd-au8810 is loaded properly ?

snd-emu10k1 use PIO.

Would you post the content of /etc/modprobe.conf ?
