Hi,
  Has anyone had CS4235 based PnP audio cards workings ?

All I get is 

isapnp0 at isa0 port 0x279: ISA Plug 'n Play device support
isapnp0: read port 0x203
wss0 at isapnp0
port 0x534/4,0x388/4,0x220/16 irq 5 drq 1,0
wss0: ad1848_probe failed
isapnp0: <Crystal Codec, CSC0001, , GAME> port 0x200/8 not configured
isapnp0: <Crystal Codec, CSC0010, , CTRL> port 0x120/8 not configured
isapnp0: <Crystal Codec, CSC0003, , MPU> port 0x330/2 irq 9 not configured

According to the data sheet this should be compatible with the CS423xB
audio parts.

Cheers,
				Mark
