Comment 21 for bug 47706

I think it's a bug, since the OSS nm256_audio kernel module from
2.6.12-9-386 works, but the later alsa modules do not, at least on my
Panasonic Let's Note CF-M1ER.

My workaround to get sound working is simply to downgrade to kernel
2.6.12-9-386 and load the nm256_audio module.
