Found the patch for this; it's in 2.6.20 # HG changeset patch # User Takashi Iwai <tiwai> # Date 1166601341 -3600 # Node ID d53318ba5eb26fbefb63d85c402cb368096436f3 # Parent e20d24388f86121d3ac6f58560e3b7acd686fd39 [ALSA] hda-codec - Don't return error at initialization of modem codec Some modem codec seem to fail in the initialization, and this stopped loading of the whole module although the audio is OK. Since it's usually a non-fatal issue, the driver tries to proceed to initialize now.

This should be fixed in the latest kernel, 2911.6.3, available at: http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/6/ Please test.
Sound worked OK on 2911.6.4, but disappeared on 2911.6.5. The only clue to any problem in dmesg: hda-intel: no codecs initialized System: Intel D101GGC motherboard, Celeron D 336 CPU Running the x86_64 version of FC6. Workaround: continue running 2911.6.4.
Fixed in 2.6.20-1.2933.fc6
