Same problem here with Intel 82801DB-Chip but only after update. Original FC5 kernel works fine.

I attached my log as well. The kernel certainly knows the card is there, yet, there is no sound.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
I would like to report identical behavior in a new install of Fedora Core 6 (FC6). The sound card is detected, snd-hda-intel is chosen, and a reasonable amount of time passes while the test wav is supposed to be playing, but no sound comes from the speakers or headphone. I checked the mixer settings and they seem reasonable. Attaching the scsconfig.log and scsrun.log in a moment. Sound worked under FC5, but because the system was preconfigured I do not know whether it would have worked with a default FC5 install, or if subsequent changes were made.

I'm not sure what you mean by "mixer settings...seem reasonable". Have you tried unmuting everything AND turning all volume controls to maximum? Often times hardware manufactures choose strange wiring configurations for their audio hardware. Unless/until the kernel is aware of that specific box, you get problems like volume and mute controls that map to the wrong input or output. My guess is that is the case here. Please try unmuting and setting max volume for all inputs and outputs, then trying to play something again. Also, please attach the output of running "lspci -n"...thanks!
John, thanks for getting back to me so quickly. I'm no expert on alsa, but based on what I've been reading on the web: # # alsaunmute 0 -v -s 100 Card 0 Driver snd_hda_intel Volume 100%...

Still, though, I can play a wav in the sense that time elapses while the sound is supposed to be playing, but I only hear silence. # /sbin/lspci -n 00:00.0 0600: 8086:27a0 (rev 03) 00:02.0 0300: 8086:27a2 (rev 03) 00:02.1 0380: 8086:27a6 (rev 03) 00:1b.0 0403: 8086:27d8 (rev 02) 00:1c.0 0604: 8086:27d0 (rev 02) 00:1c.1 0604: 8086:27d2 (rev 02) 00:1c.2 0604: 8086:27d4 (rev 02) 00:1d.0 0c03: 8086:27c8 (rev 02) 00:1d.1 0c03: 8086:27c9 (rev 02) 00:1d.2 0c03: 8086:27ca (rev 02) 00:1d.3 0c03: 8086:27cb (rev 02) 00:1d.7 0c03: 8086:27cc (rev 02) 00:1e.0 0604: 8086:2448 (rev e2) 00:1f.0 0601: 8086:27b9 (rev 02) 00:1f.2 0101: 8086:27c4 (rev 02) 00:1f.3 0c05: 8086:27da (rev 02) 01:0a.0 0c00: 1217:00f7 (rev 02) 01:0a.2 0805: 1217:7120 (rev 01) 01:0a.3 0180: 1217:7130 (rev 01) 03:00.0 0280: 8086:4222 (rev 02) 07:00.0 0200: 11ab:4362 (rev 20) Do you think this might be significant?: # dmesg | grep ALC hda_codec: Unknown model for ALC861, trying auto-probe from BIOS... I was searching around online, and noticed this thread on the alsa bugtrack. Think it might be relevant?: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2174 Thanks *very* much!
Created attachment 142587 [details] lspci output I just installed fc6 on my Dell Latitude D800 and I am having the same problem with my sound card: Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01).
Created attachment 142590 [details] scsconfig.log scsconfig.log for Dell Latitud D800 with Intel 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) sound card using Fedora Core 6

Looks like we may need support for the ALC861 codec to resolve this issue.
