With 2.6.34-rc1+ my laptop (Sony Vaio VGN-FS215S) can't reproduce any sound. All controls are missing from alsamixer and this message is found in dmesg:

  hda_codec: cannot build controlsfor #0 (error -22)

Kernel config is attached, and the output from alsa-info.sh follows:

Does the patch below fix?

Yes, it does.

Thanks for checking. The fix is merged in sound tree.
