No working sound device on Lenovo T61

Hi,

I'm having trouble running the sound device on my Lenovo Thinkpad T61.

Symptoms: I don't hear sound when using aplay. When using moc I get

"FATAL_ERROR: No valid sound driver!"

When running moc as root it starts fine, but I can't hear any sound as well.

What I've done so far:

- unmuted all channels. But below the PCM bar, there is no mute/unmute button
- added myself to group "audio"
- added "thinkpad-acpi snd-hda-intel snd-pcm-oss" to MODULES in /etc/rc.conf
- added "alsa" to DEAMONS in /etc/rc.conf
- created /etc/modprobe.d/alsa.conf with

options snd slots=snd-hda-intel
options snd-hda-intel model=thinkpad

But all fails.

Thanks in advance for your help.

Maybe useful outputs:

Why is thinkpad_acpi displayed in the last line? Is this a problem?

Re: No working sound device on Lenovo T61

I don't know the cause to your problem. I too have a T61 and here is the output for the commands you posted. Here everything works.

$ ls -l /dev/snd

EDIT: The difference I see is that you have some OSS mentioned there.

Re: No working sound device on Lenovo T61

The difference I see is that you have some OSS mentioned there.

Thats because I'm loading snd-pcm-oss on startup. (because ALSA's wiki page says so).
Removing it from MODULES in /etc/rc.conf has no effect, besides that these oss outputs are missing.

EDIT: But one thing is interesting:  The column "Used by" of your lsmod output states that snd_hda_intel is used by two other modules. According to my lsmod output snd_hda_intel is used by no other modules.
That can't be right.
