From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: I updated my machine(clean install) from FC1 to FC2T3. I fully patched the machine and I have no audio. The soundcard-detection applet detects an Intel 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller. It appears to use module: snd-intel8x0 After playing around, I opened the mixer and found PCM2 set to the lowest possible slider position. I moved the slider to the mid-point and I got audio again. Version-Release number of selected component (if applicable): alsa-lib-1.0.3a-2 How reproducible: Always Steps to Reproduce: 1. Run soundcard detection applet 2. Play test sound 3. Actual Results: No audio detected due to initial configuration of PCM2 to 0 Expected Results: Standard audio playback. Additional info: /etc/modprobe.conf alias eth0 e1000 alias scsi_hostadapter ata_piix alias snd-card-0 snd-intel8x0 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 usb-controller ehci-hcd alias usb-controller1 uhci-hcd
Please try the final release.
Yes. It still is an issue in the release. I have updated this to reflect this information.
I also see this bug on a clean FC2-final install. My modprobe.conf is identical to the op's. However system-config-soundcard detects "Intel 82801DB (ICH4) AC'97 Audio Controller," which is how lspci -vv reports it, too. system-config-soundcard also says on stdout... Simple mixer control 'PCM',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 23 [74%] [on] Front Right: Playback 23 [74%] [on] ...although the real mixer control is PCM-2 on the OSS mixer tab, labeled "Analog Devices AD1981B [Audio Mixer(OSS)," of gnome-volume-control. This slider is the only one which has any effect. In particular, the master volume slider has no effect. None of the sliders on the Alsa mixer tab, labeled "Intel 82801DB-ICH4 [Alsa Mixer]," have any effect, either. I haven't had any success at all with CD audio as a source. (Curiously the Alsa tab has two sets of CD sliders. There's only one CD.) Possibly related is this snippet from /var/log/messages: bonobo-activation-server (root-2464): iid OAFIID:BrokenNoType:20000808 has a NULL type bonobo-activation-server (root-2464): invalid character '#' in iid 'OAFIID:This#!!%$iid%^$%_|~!OAFIID_ContainsBadChars' modprobe: FATAL: Error running install command for sound_slot_1 modprobe: FATAL: Error running install command for sound_slot_1
BTW: Bugs 123631 and 124497 appear to be duplicates of this one.
Oops. I lied. The PCM slider on the Alsa mixer _does_ work. The masters still have no effect, though.
If the volume sliders in the alsa mixer aren't having an effect, that sounds like an alsa driver bug.
Bug 122557, 122953, bug 123389, bug 123586, bug 123631, and bug 124497 all seem to be describing the same problem. Some of these are already assigned. Bug 123631 seems to be the best-documented, so I am putting additional diagnostic info there. Someone with the right permissions should probably mark the others as duplicates as appropriate.
Bug 123631 Comment #17 lists the options to snd-intel8x0. options snd-intel8x0 ac97_quirk=2 appears to have solved most of my mixer-related problems. There are still two sets of CD sliders on the Alsa mixer, despite there being only one CD channel. (At least there's only one CD connector on the motherboard.)
I am moving this on to FC3. Just did a clean install of FC3 and I had zero audio during the "sound card" detection portion of the firstboot. When I logged in, I adjusted the "Line" volume to resolve this issue. Do we acutally want to fix this in the installer, or just put something in a FAQ and close it?
I actually did a fresh install of FC3 on a different laptop (a Toshiba) and got zero sound...though it turns out that was because there's a volume control manifested as a physical knob on the outside of the laptop that was set too low. It would be nice, at the part of the install when the sound is tested, to remind users to check any hardware volume controls. And perhaps show them the software volume settings and allow them to turn up the volume (or to better detect settings and do this automatically). -Beland

However they play the sound. Rosegarden plays midi. However all of these programs have one thing in common: The sound is so low you can barely hear it. Gnome mixer has all levels up as high as they can go, but still none play loud enough to hear, unless your ear is next to the speakers. I'm not sure why sound is so soundless. All the modules look like they are right. Guess I'm downgrading to 2.6.10 to get sound, but I'll test this out to see what else it breaks.
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.
I did not experience this issue with FC4. This ticket can be closed.
thanks. as the FC3 & FC4 kernels are pretty much identical now, this should be fixed in both.
