Problems with 2.4.24 Via audio driver.

Can anyone offer any possible debug tips for tracing a problem with the Via
Audio driver under 2.4.24?

Before anyone asks, I already tried using the email address in the maintainers
list (linux-via@xxxxxxx) - that address is invalid - no such user.

The problem is that the audio driver appears to not be initializing the DSP
correctly. Thus, I get no audio out.

Here is the relevent lines from dmesg:

root@db:~# dmesg | grep -i via
PCI: Using IRQ router VIA [1106/3177] at 00:11.0
via-rhine.c:v1.10-LK1.1.19 July-12-2003 Written by Donald Becker

eth0: VIA VT6102 Rhine-II at 0xa800, 00:0c:6e:74:2a:03, IRQ 9.
agpgart: Detected Via Apollo Pro KT400 chipset
VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci00:11.1
Via 686a/8233/8235 audio driver 1.9.1-ac3
via82cxxx: Six channel audio available
via82cxxx: timeout while reading AC97 codec (0x8000000)
via82cxxx: board #1 at 0xE000, IRQ 9

Note that I already have tried the following in via_ac97_wait_idle
(via82cxxx.c): changing the usleep value from 15 to 150 - no difference.

Here is the dump from lspci -vv
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio

Thanks for your time and help!
