Release:	FreeBSD 4.1-STABLE i386

Organization:

Accessibility Research Group for the Visually-Impaired

Environment:

CPU: Pentium III/450Mhz
Mem: 128Mb
MB: AOpen AX6BC-R
Sound: YAMAHA Waveforce192D, SB VIBRA16X

Description:

In my system the YMF724 based board (YAMAHA Waveforce 192D) is installed. I tried to make the kernel with the option
device pcm
but it fails to initialize as follows:

pcm0: <Yamaha DS-1E (YMF724F)> mem 0xed020000-0xed027fff irq 11 at device 9.0 on pci0
pcm0: ac97 codec init failed

How-To-Repeat:

In the same hardware environment, make kernel with the above configuration and reboot. It may (or not) occur.

Fix:

In /sys/dev/sound/pci/ds1.c there is the following code:
if (sc->type == 8)
DELAY(400000);
When I commented out the 'if' line and increased the delay to 500000, the chip is correctly initialized.
