Comment 5 for bug 697383

There is a patch upstream in the recently released kernel 3.1-rc1 which might fix this problem:

commit b68785714b67079385188323631b05a8f9093675

    ALSA: hda - Add Realtek ALC269VC codec support

    Add the support of ALC269VC codec.
    Also delete the unnecessary codec_variant type enum list:
    now only three variants (ALC269VA ALC269VB ALC269VC) are needed.

    In addition, added some aliases:
     - Add ALC269VB alias name ALC277
     - Add ALC269VC alias name ALC259 ALC281X
     - Add ALC269VC for Lenovo device 0x21f3 name ALC3202

Note the alias name ALC259.
