Hi, I use Mandrake but had similar problems. You must use the CS4236 driver =

from alsa (or so I found). This driver MUST be passed options so in=20
/etc/modules.conf you must have

alias snd-card-0         snd-card-cs4236
alias sound-slot-0       snd-card-0
options snd-cs4236 port=3D0x530 cport=3D0x538 irq=3D5 dma1=3D1 dma2=3D0 =
isapnp=3D0


The reason for useing a different driver is that the CS4610 has an=20
emulation of the CS4231/2 and CS4239 cards and the alsa CS4236 driver=20
supports the CS4239 emulation of the CS4610 that is in the TP600E (or in=20
mine anyway).

As for the reversion to the CS4610 when you reboot, have you got a deamon=20
running that looks for new hardware. In Mandrake 9.2 I had to switch off=20
the hotplug deamon or it always found the CS4610 card and changed the=20
settings.

So in summary
switch off hotplug and ensure the alsa driver is passed the correct options

Cheers
Nigel
