Sound problems in 2.3.50

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/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996

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.

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

Thanks for your help,

Well, Christoph Hellwig is apparently adapting the sound drivers to the newer module initialization scheme, which should make it easier to just configure drivers into the kernel. An additional change was the removal of /dev/sndstat and /proc/sound, so that explains that part of the problem.

Well, from what I can tell, your opl3sa2 append line for lilo.conf should have gotten things working, but there was some talk of general sound issues with 2.3.50 on linux-kernel. Could you try 2.3.51 and see if that works? It contains a bunch more patches to the sound system.

How come /proc/sound was removed? Is there an alternative place to get that information?

I've been watching for sound articles on linux-kernel, and looks like there are changes in 2.3.51 which may effect my problem. But sadly, 2.3.51 wont build on my system, so I'm just waiting for next week and
2.3.52, or 2.4-pre-1, or whatever. When I get a new kenel built,
I'll report back.

Thanks,
