This chip is software configurable. In Thinkpads, the BIOS sets up the chip if fast boot is disabled. If fast boot is enabled, the chip is disabled until a PnP driver enables it. As both the OSS and the ALSA module do not support PnP discovering of this chips in thinkpad, a isapnptools like user space configuration approach described in [[CS4239 in PnP mode]] could be used.

CS4239

This is a Cirrus Logic Audio controller

Note: This sound chip is paired with a PCI CS4610 audio controller, only one sound driver should be loaded, preferably the PCI driver.

Features

  • Chipset: CS4239
  • Interface: ISA 16bit

Linux OSS driver

This sound chip is supported by the cs4232 kernel module. Use the following options line when loading this module:

options cs4232 io=0x530 irq=5 dma=1 dma2=0

Linux ALSA driver

This sound chip is supported by the snd-cs4236 kernel module. Use the following options line when loading this module:

options snd-cs4236 snd_index=0 snd_port=0x530 snd_cport=0x538 snd_isapnp=0 snd_dma1=1 snd_dma2=0 snd_irq=5

PnP issues

This chip is software configurable. In Thinkpads, the BIOS sets up the chip if fast boot is disabled. If fast boot is enabled, the chip is disabled until a PnP driver enables it. As both the OSS and the ALSA module do not support PnP discovering of this chips in thinkpad, a isapnptools like user space configuration approach described in CS4239 in PnP mode could be used.
