Based on this information, I'll go ahead and add your device ID to the codec driver so you won't need to add the "model=" modprobe parameter (see attached patch). The probe_mask issue will need more work to figure out what exactly is going on. I wonder if it might be acpi related?

I have been without sound using Fedora Core ever since the 2.6.16 or 2.6.17 kernel update (2.6.16 crashed during initialization, so I could not tell whether sound worked or not). It had worked well through the 2.6.15 Fedora kernels. I finally sat down tonight to work the problem as hard as I could and happened upon Eric and Tobin's timely exchange.
First, simply adding probe_mask=1 to the snd-hda-intel options worked for me as well; I did not end up having to specify a specific model.
Second, I too was seeing a LONG hang when trying to do: cat /proc/asound/card0/codec#0 but now with the probe_mask=1, I do not see this.
If it helps, the alsa-info.sh output for my system is at http://pastebin.ca/496293 If it makes any difference, I'm not sure which model I had specified on the modprobe line at the time I captured this output.
One thing I do notice is that after adding probe_mask=1, aplay -l does not show the Si3054 Modem which shows up in the alsa-info output.
Thanks for the help you gave in the thread with Eric.

Interesting. I've seen similar reports that probe_mask helps. Do you disable the modem codec on BIOS or is it enabled?
If this happens even though it's enabled on BIOS, we'd need a blacklist of non-working devices, or a more robust probing routine...
