Talk:CS4297

This chip does NOT seem to be in my x20; is it really supposed to be in there? Capybara 04:08, 31 Oct 2005 (CET)

Run lspci, do you see an Intel AC'97 Audio Controller? That is a generic interface to a AC'97 audio codec, in your case the CS4297A according to tawbook --Tonko 04:59, 1 Nov 2005 (CET)

Problem using snd_intel8x0 instead of snd_cs46xx

I've T21. I'am using snd_cs46xx as a sound driver, but it has bad behaviour when doing hibernation. So i tried the intel8x0 driver, but it doesn't work! Does my ThinkPad have a different soundcard? lspci:

       00:05.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01)
       Subsystem: IBM Unknown device 0153

modprobe snd_intel8x0 works (i've rmmod'ed all sound related modules before), lsmod shows it and it's dependecies, but cat /proc/asound/cards shows no cards. dmesg says nothing about sound. Do I need to load firmware, specify module params or so? --Strohel 18:59, 12 November 2006 (CET)

At least my T20 has an Intel 440BX chipset, which does not include an Intel AC'97 controller: snd-intel8x0 does not work for me.....

Suspend resume issue on 600X

Using a ThinkPad 600X, suspend and resume nets no sound. I have to rmmod cs_46xx, which I cannot unload unless I log out of X.

Any tips on automating? --Whizkid 23:33, 18 December 2006 (CET)

Disabling CONFIG_SND_CS46XX_NEW_DSP works for me. The driver continues to work after resume. However, according to powertop it causes a lot of interrupts after resuming till you rmmod/modprobe it. This might drain battery more quickly........
