>From the above, it looks like your card, while using the Intel HD Audio spec, is using the Conexant codec. But you don't have support for that in your kernel, or at least, not in the options you quoted (CONFIG_SND_HDA_CODEC_CONEXANT). Try adding that. If that doesn't work, try adding support for all the codecs listed under the Device Drivers -> Sound card support -> ALSA -> PCI Sound Devices -> Intel HD Audio sub-menu and see if that fixes things up. Also, at a guess, the two "codecs" are going to be the Conexant codec for the sound card, and the SigmaTel for the modem. But for the ATI HDMI, I'm used to seeing that referring to video cards and monitors; see http://en.wikipedia.org/wiki/Hdmi. HTH John Moe
