Comment 23 for bug 445889

I confirm that installing http://people.canonical.com/~diwic/temp/alsa-intel-hda-optiplex-dkms_1.0.23_all.deb fixed the problem with no sound on Sony VAIO VPCEB1M1E, in Ubuntu Lucid 10.04.

Thanks for taking care of that bug!

BTW, bug 534372 seems to be a duplicate of this one, as I got the exact same symptoms, and the workaround from that bug (using hda-verb) works for me.
