|
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 a ThinkPad, a configuration script like this one may be used. See also this page for more information.
