From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.7.8-1.3.1 Description of problem: Having installed the latest kernel patches vmlinuz-2.6.12-1.1372_FC3 the sound stopped working. The volume control on gnome panel behaved oddly, reverting to its original position when I tried to change it. Reverting to 2.6.11-1.35_FC3 cured the problem (for me) cat /etc/modprobe.conf # Note: for use under 2.4, changes must also be made to modules.conf! alias eth0 natsemi alias usb-controller uhci-hcd alias ieee1394-controller ohci1394 alias snd-card-0 snd-emu10k1 install sound-slot-0 /sbin/modprobe --first-time --ignore-install sound-slot-0 && { /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :; } remove sound-slot-0 { /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :; } ; /sbin/modprobe -r --first-time --ignore-remove sound-slot-0 Version-Release number of selected component (if applicable): kernel-2.6.12-1.1372_FC3 How reproducible: Didn't try Steps to Reproduce: 1. You need a soundblaster audigy 2, an amd athlon 1700, gigabyte motherboard 2. install the latest kernel 2.6.12 and go to the bbc website and try to listen to something 3. Actual Results: no sound, volume control behaving oddly Additional info:
I have just booted this kernel again and tried playing an mp3 with xmms. The same problem occured: The volume control on the panel is at zero, and when I move it up it springs back to zero again. Using gnome panel 2.8.1
If for no other reason than another data point, I am having the same problem (no sound) with a "SB Live" card and the 2.6.12-1.1372_FC3 kernel. Intel P4 system with: [snip] [root@hellcat ~]# cat /proc/asound/cards 0 [Unknown ]: EMU10K1 - SB Live [Unknown] SB Live [Unknown] (rev.10, serial:0x80221102) at 0xd880, irq 9 [root@hellcat ~]# cat /etc/modprobe.conf alias eth0 dmfe alias snd-card-0 snd-emu10k1 options snd-card-0 index=0 install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-emu10k1 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-emu10k1 alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd alias char-major-195* nvidia [snip] As noted in comment 0, sound works fine with the 2.6.11-1.35_FC3 kernel.
I also have noticed problems with the emu10k1, and could get no mic input. I noticed that the alsamixer and Gnome Volume Control 2.8.0 no longer listed "Mic boost (+20db)" as part of the controls. Going back to 2.6.11-1.35_FC3 Kernel fixed it. No amount of futzing with modules modprobe.conf would fix it. $ cat /proc/asound/cards 0 [Audigy ]: Audigy - Sound Blaster Audigy Sound Blaster Audigy (rev.3, serial:0x511102) at 0xd400, irq 11
I'm also having the same issue. [peggy@fedorajim ~]$ rpm -q kernel kernel-2.6.11-1.14_FC3 kernel-2.6.11-1.27_FC3 kernel-2.6.11-1.35_FC3 kernel-2.6.12-1.1372_FC3 The only kernel that plays sound is kernel-2.6.11-1.27_FC3 Since this is my wifes PC and she likes to listen to music all the time I have had to edit grub to boot to this kernel only. [peggy@fedorajim ~]$ cat /etc/modprobe.conf alias eth0 e100 alias snd-card-0 snd-intel8x0 options snd-card-0 index=0 install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0 alias char-major-81 bttv alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd The volume control on the panel is at zero, and when I move it up it springs back to zero again. [peggy@fedorajim ~]$ rpm -qa | grep alsa alsa-driver-1.0.9rf-39.rhfc3.at alsa-lib-devel-1.0.6-8.FC3 alsa-kmdl-2.6.11-1.14_FC3-1.0.8-36.rhfc3.at alsa-utils-1.0.6-3 alsa-lib-1.0.6-8.FC3 alsa-kmdl-2.6.12-1.1372_FC3-1.0.9rf-39.rhfc3.at Could the alsa drive be causing the issue?
the alsa userspace is quite closely tied to the kernel side. You have 1.0.9 kernel modules, and 1.0.6 userspace, so quite likely this is problematic. Try and reproduce with all the rhfc3.at alsa rpms removed, and using just the ones from FC3 updates
(In reply to comment #5) > Try and reproduce with all the rhfc3.at alsa rpms removed, and using just the > ones from FC3 updates I have only the FC3 rpms and still experience the problem. [mark@hellcat ~]$ rpm -qa | grep -i alsa alsa-lib-1.0.6-8.FC3 alsa-lib-devel-1.0.6-8.FC3 alsa-utils-1.0.6-3
I too have only fedora alsas. If the problem is the mixer then presumably using a different mixer, i.e. the consol based one (alsamixer), would fix it? I will try it a bit later. # rpm -qa | grep -i alsa alsa-lib-devel-1.0.6-8.FC3 alsa-utils-1.0.6-3 alsa-lib-1.0.6-8.FC3
I get identical results to Reib (works with 2.6.11-1.35_FC3 but fails with 2.6.12-1.1372_FC3 as reported in #4 above) with regard to packages. Yum pointed at the Fedora repositories shows no later version than what I have, save for the debuginfo package I have never installed. Could this be a yum dependency or repository problem with FC3 updates? $ rpm -qa | grep -i alsa alsa-utils-1.0.6-3 alsa-lib-1.0.6-8.FC3 alsa-lib-devel-1.0.6-8.FC3 $ uname -r 2.6.11-1.35_FC3 $ yum list alsa\* Installed Packages alsa-lib.i386 1.0.6-8.FC3 installed alsa-lib-devel.i386 1.0.6-8.FC3 installed alsa-utils.i386 1.0.6-3 installed Available Packages alsa-lib-debuginfo.i386 1.0.6-8.FC3 updates-released
I have just booted the latest kernel and sound is now working. I didn't even use the consol mixer. I am at a loss to explain why, unless it has been fixed by some FC3 update which went in since I raised the bug.
I was able to get things working too with 2.6.12-1.1378_FC3 kernel, but only after one magical step: [root@hellcat ~]# system-config-soundcard I have no idea what this utility does ... well, other than making sound work.
