Re: [Alsa-user] VIA 82xx chip & snd_hda_intel no sound and codec is Generic 1106 ID1708?

[Tobin D. <td...@ds...>]

The best thing to do is to try the latest driver.  I'm not sure if it
was added before or after 1.0.16, but your codec is supported in the
current driver code base.  Download from alsa-project.org.
