tecra 8000 - sound on version 3.8.1

I have used v3.4 since it was available and had never been able to get the sound working - then I came across a post on this forum which listed the following:

From root

insmod soundcore
insmod sound
insmod mpu401
insmod ad1848 iox530 irq=5 dma=1 dma2=0
insmod opl3 io=0x388

Low and behold the sound works - albiet at a low level and I can't seem to find any way of upping the volume within Linux.

So with renewed interest last night I downloaded version 3.8 and gave it a try

I have not had any "error" messages with v3.4, but as v3.8 boots I get PCI: cannot allocate resource region4 of device 0000:00:05:1

The Computer boots as normal

when I try to enter insmod soundcore I get the following message:

insmod: can't read "soundcore" - no such file or directory

Has this been removed on the later release, or just moved - and if it's the latter how do I get to it from the shell ?, if it's the former does this mean no sound at all.

I could stick with v3.4 but my next years project is to get a wireless network card to work
