Hello. I get the same error(from bellow) with quake3 by using SUSE10.3 on a Gigabyte P35 DS3R board(also with Realtek ALC889A). I did not try yet, but I suppose I will have the same problem with Enemy Territory

Anyone could hive some hint?
Code:
------- sound initialization -------
Could not mmap dma buffer PROT_WRITE|PROT_READ
trying mmap PROT_WRITE (with associated better compatibility / less performance code)
/dev/dsp: Input/output error
Could not mmap /dev/dsp
