To configure the CS4239 sound chip via PnP, use the following script1 (Tested on a ThinkPad 600E). It is meant to be used as install script with modprobe. An example modprobe.conf snippet follows.
Save this script as /usr/local/sbin/soundcard-on.
The Script
#!/bin/bash # Sound-via-pnp-script for Thinkpad 600E and possibly other computers with onboard # CS4239/CS4610 that to not work with the PCI driver and are not recognized by the # PnP code of snd-cs4236 # search sound card pnp device for dev in /sys/bus/pnp/devices/* do grep CSC0100 $dev/id > /dev/null && WSSDEV=$dev grep CSC0110 $dev/id > /dev/null && CTLDEV=$dev done # activate devices (Thinkpad boots with devices disabled unless "fast boot" is turned off) echo activate > $WSSDEV/resources echo activate > $CTLDEV/resources # parse resource settings { read read bla port1 read bla port2 read bla port3 read bla irq read bla dma1 read bla dma2 # Hack: with PnPBIOS: ports are: port1: WSS, port2: OPL, port3: sb (unneeded) # with ACPI-PnP:ports are: port1: OPL, port2: sb, port3: WSS # (ACPI bios seems to be wrong here, the PnP-card-code in snd-cs4236.c uses the # PnPBIOS port order) # Detect port order using the fixed OPL port as reference if [ ${port2%%-*} = 0x388 ] then # PnPBIOS: usual order port=${port1%%-*} oplport=${port2%%-*} else # ACPI: mixed-up order port=${port3%%-*} oplport=${port1%%-*} fi } < $WSSDEV/resources { read read bla port1 cport=${port1%%-*} } < $CTLDEV/resources # load the module modprobe --ignore-install snd-cs4236 port=$port cport=$cport fm_port=$oplport irq=$irq dma1=$dma1 dma2=$dma2 isapnp=0 index=0 && /lib/alsa/modprobe-post-install snd-cs4236
modprobe Configuration
Add these lines to /etc/modprobe.conf or /etc/modprobe.d/cs4236pnp:
# Kill any attempts from hotplug or discover to load the PCI driver install snd-cs46xx /bin/true # Set up PnP before loading ISA driver install snd-cs4236 /usr/local/bin/soundcard-on
