Sound problems in 2.3.50

[Dave Caswell <davec@asylum.apocalypse.org>]

I've got no sound in 2.3.50.

My Toshiba notebook has a OPL3-SA3 chip which was working with
kernel 2.3.49 sound drivers built into the kernel.  

With 2.3.50, none of the sound devices including /dev/sndstat worked.

After checking the log files, I saw the warning that the opl3sa2
parameters needed to be set, I added an append line to my lilo.conf.
Mar 10 11:39:02 krypton kernel: ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996 
Mar 10 11:39:02 krypton kernel: MSS: I/O port conflict 
Mar 10 11:39:02 krypton kernel: mpu401: I/O port ffffffff already in use 
Mar 10 11:39:02 krypton kernel:  
Mar 10 11:39:02 krypton kernel: opl3sa2: io, mss_io, irq, dma, and dma2 must be set. 

Added to lilo.conf:
append = "opl3sa2=0x370,5,1,0,0x530,0x330"

Still no sound functions. So I checked the log again:

Mar 10 13:39:56 krypton kernel: ad1848: must give I/O , IRQ and DMA. 

and added this to my lilo.conf
append = "ad1848=0x388,5,1,0,0"

Still no sound, although I did have some mixer settings now.

Here's what /dev/sndstat claims, with my 2.3.49 kernel.

Synth devices:

Midi devices:

Mixers:

So, is there a new configuration file that I need to tweak? Or is
something broken?

Thanks for your help,
