SOUND: ALSA Sound Drivers - Cirrus Logic|CS4614/22/24 [CrystalClear SoundFusion Audio Accelerator]
Get the drivers at http://www.alsa-project.org . Configuration obtained from http://talisman.mv.com/laptop.html . Specs on the chipset http://www.cirrus.com/design/products/overview/index.cfm?ProductID=40 .
The sound chip is a CrystalClear SoundFusion Audio Accelerator (CS4614/22/24). This does not seem to be support by the OSS modules in RedHat, however the ALSA Project does have support for this chip. Download the ALSA drivers, uncompress them, change to the ALSA directory and run "./configure --with-cards=cs461x", then a "make", and "make install". From there the module(s) can be inserted using insmod or modprobe. It seems that this sound card can't handle the PCI Bus Power Management feature, so in order to get this working properly you'll need to disable that. From the ThinkPad setup (F1 after turning it on), choose 'config' and then 'power', scroll to the bottom and disable the 'PCI Bus Power Management' feature. I can now play mp3 etc... without any trouble, here's the /etc/conf.modules portion for Alsa:
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-card-cs461x
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-12 snd-pcm-oss |
