From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3 Description of problem: I have a sound blaster 16 PCI card and have run it under Red Hat 8,9 and up until the latest kernel in FC3 with no problems. I upgraded the kernel yesterday using up2date and upon reboot was unable to get the sound working. It appeared that the kernel found the sound card with no problems, but that it was stuck muted. I have seen this before and usually can use aumix, or alsamixer to fix this problem. When going into alsamixer for example one of the channels usually is called MASTER. With the upgrade kernel that MASTER channel was gone and wasn't available to be selected. The MASTER channel also wasn't even showing up in the "Volume Control" application in GNOME. My also version is below. Executing: rpm -qa | grep alsa alsa-utils-1.0.6-3 alsa-lib-1.0.6-8.FC3 alsa-lib-devel-1.0.6-8.FC3 I rolled back to my previous kernel which is: 2.6.10-1.770_FC3 and the problem went any. Executing alsamixer shows a MASTER channel and the sounds works flawlessly once again. I'm not sure if this is problem with the kernel or alsa but am surprised when I booted into the old kernel the problem was fixed! Version-Release number of selected component (if applicable): kernel-2.6.11-1.14_FC3 How reproducible: Always Steps to Reproduce: 1. Sound Blaster 16 PCI Card 2. alsa 1.0.6-8.FC3 3. kernel-2.6.11-1.14_FC3 No sound output and Master channel missing from the volume control, aumix and alsamixer Actual Results: MASTER channel not appearing the aumix, alsamixer or the gnome "volume control". No way to turn the volume up. Card appears to be recognized but no sound is played. Expected Results: Sound should have been played. Booting into the old 2.6.10-1.770_FC3 #1 Thu Feb 24 14:00:06 EST 2005 kernel fixed the problem. Additional info: With old kernel executing: "amixer" gives the following line: Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 31 [100%] [on] Front Right: Playback 31 [100%] [on] However, installing and booting into kernel-2.6.11-1.14_FC3 the Master definition above is missing and gives only gives only the follwing. Set this volume to 100% has no effect on the sound output. Simple mixer control 'Master Mono',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 0 [0%] [off]
Hi! Just wanted to let you know that tonight I upgraded to my my kernel to: [justin@panda ~]$ uname -a Linux panda 2.6.11-1.27_FC3 #1 Tue May 17 20:27:37 EDT 2005 i686 i686 i386 GNU/Linux and the problem seems to be resolved in this kernel. I have no problems with the mixer and getting the sound to work. It all works just fine. We can probably close this issue out. Thanks, Justin
Scratch that last posting. I rebooted this morning at the problem is back again. Volume control does not show up. Looks like we might have an intermittent problem. Please don't close this bug out. Thanks, Justin
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
