Description Mark Eggers 2005-04-12 20:30:14 UTC
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1 Description of problem: Installation of the new kernel from kernel-2.6.10-1.770_FC3 proceeded without incident. Upon booting into the new kernel and bringing up KDE, I noticed that I had no sound. I investigated with gnome-volume-control, and found that my old sound card (onboard Intel card) was set as the default sound card. This is odd since that sound card is disabled in BIOS (Dell 8200). I then took a look at /etc/modprobe.conf. Several changes had been made to the file. The line: alias snd-card-0 snd-cs46xx was replaced with: alias snd-card-0 snd-card-0 The following line was removed: alias sound-slot-0 snd-card-0 This is strange, since I keep /etc/modprobe.conf under RCS, and only do a co -l when I make changes. Otherwise it is checked out without locking, so the file is read-only. At any rate, I edited the file, made the appropriate changes, and sound is back to normal. Version-Release number of selected component (if applicable): kernel-2.6.11-1.14_FC3 How reproducible: Always Steps to Reproduce: 1. Upgrade kernel 2. Lose sound 3. Notice that /etc/modprobe.conf has been modified Actual Results: /etc/modprobe.conf has been edited by the rpm install, and my PCI sound card (Turtle Beach Santa Cruz) is no longer the default sound card. Expected Results: Existing /etc/modprobe.conf entries should not be changed by a kernel installation. Additional info:
Comment 1 Rik van Riel 2005-04-12 20:43:28 UTC
This is probably due to /usr/sbin/module_upgrade running in the %post script. Not sure if it's a bug (though it sure looks like it in this case), but reassigning to the package containing module_upgrade just in case.
Comment 2 Bill Nottingham 2005-04-13 03:29:45 UTC
OK, it's tripping up on the obsolete: alias sound-slot-0 snd-card-0 line, which isn't actually needed. It's interpreting it as an older 2.4 alias.
Comment 3 Mark Eggers 2005-04-13 09:32:17 UTC
OK, and I took a look at my /etc/sysconfig/hwconf file to remove the lingering onboard sound system. Then the only thing that is left is the changing of the alias snd-card-0 snd-cs46xx with alias snd-card-0 snd-card-0 It's sounding more like I need to do some cleanup from the upgrade (Fedora Core 2 to Fedora Core 3 - long time ago) than an actual bug. I'll see if I can reproduce this when the next kernel comes out after I do the following: 1. Remove currently unused hardware from configuration and tell kudzu not to add it back in. 2. Remove the alias sound-slot-0 snd-card-0 line Then see what happens . . .
Comment 4 Erik P. Olsen 2005-10-10 15:46:52 UTC
I have noticed the same odd behaviour latest when updating the kernel to version 2.6.12-1.1378_FC3. In my case the lines: alias sound-slot-0 snd-card-0 options snd-card-0 index-0 were removed and no sound produced and alsamixer would not see my sound card. Adding the lines brought back the sound.
Comment 5 Matthew Miller 2006-07-10 21:17:47 UTC
Fedora Core 3 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thank you!
Comment 6 Mark Eggers 2007-08-01 04:31:53 UTC
This bug should be closed, as I reported it to be resolved in fc4 and beyond. Thank you for your time and effort.
Comment 7 Rik van Riel 2007-08-01 04:34:55 UTC
Closed as requested.
