no sound on Thinkpad A30 (solved)

#1 Post by mclien »

Got this for my mom and it should get puppy.

liveCd boots no problem, except the sound. I searched around in the forum but one tip (disable quick boot in bios) doesn't work and the other onece (adding a modprobeline) doesn't fit my sound chip.
It has been reported to be an i810 (intel).
So can someone pass me the right modprobeline for that?

Thanks in advance.

I didn't find a modprobe line, but here are two links saying exactly what you have:

You have the Cirrus Logic (Crystal) CS4299 chipset, supported by the OSS i810_audio module, thus -

modprobe i810_audio

no success so far :cry:

modprobe doesn't give me an error, so perhaps I've to chek if the hardware has any problem....

Ideas how to check, if the hardware is ok?
edit:
for hardware testing I installed the 'other' OS, so now I know the sound works and the hardware is OK.
Thanks for any other Idea... (Moms birthday is the 29th of October...)
2.update:
kubuntu live (ubuntu with kde) works (but is useing alsa.
so now I'm runniing out of ieads...

Random thought, have you tried messing with the BIOS settings? Thinkpads are odd like that on occassion.

I solved it, however I'm not really sure how.
As I was setting up the modem, with a wrong phonenumber of the provider. This gave me back an error, which was a friendly voice telling me that this number doesn't exist or at least wasent a data line.

So the sound was be expected to work. The volume wasn't set to zero, but it dosen't give me any sound until I just moved the sliders a bit up and down. Since then it worked propperly.
Maybe these Thinkpads just want to figered around a bit. :wink:

@keenerd
nevertheless I agree totally with you about what IBM calls 'BIOS'.
(I often spend 'some' time just to find WHERE to set things in this BIOSes, perhaps someone makes a LinuxBIOS for this)
