Thinkpad T61 ALSA problems

I'm experiencing problems with alsa on my laptop. Every second or third boot ALSA doesn't even recognize my soundcard and when it does my microphone doesn't work (in Skype and so on..). The sound card is:

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

The modules are loaded correctly...

Re: Thinkpad T61 ALSA problems

Can anyone please help me. With the new kernel update alsa (for now), always recognizes my audio card but i still don't get any sound. And even when my sound uotput worked, my internal mic never worked, i tryed it with skype... Please, can someone just point me in the right direction, because i don't know what to do anymore...

Re: Thinkpad T61 ALSA problems

Do you get sound from headphones?

I didn't get any sound from speakers with 2.6.28 & snd_intel_hda, but the headphones worked. Compiling newer version of alsa-driver worked for me. You can get the package from here: http://ftp.kernel.org/pub/linux/kernel/ … sa-driver/

Re: Thinkpad T61 ALSA problems

i have no idea if this will help, but i found this old thread:

http://bbs.archlinux.org/viewtopic.php?id=35148

or from this site:

http://lambda.uta.edu/T61/

To make the internal microphone work (for skype, etc) use:

alsamixer -V all

set input source to Internal Mic, maximize Internal Mic, and set Mic to 70%. Then open Sound Control dissable Internal Mic and set Microphone to 70%.

Re: Thinkpad T61 ALSA problems

I've tried it all but the mic still doesn't work. Does anyone else have this audio card? I don't know is it problem with it or with the configuration. it is driving me crazy!
