Description of problem: Version-Release number of selected component (if applicable): How reproducible: Every time Steps to Reproduce: 1. Perform a fresh install. Update if necessary to system-config-soundcard-2.0.6-6.fc7. 2. Attempt to use it. Actual results: * No sound, not even from system-config-soundcard. * Nothing relevant shows up in modprobe.conf. For FC6, modprobe.conf looks like: -------------------------------------------------- alias eth0 via-rhine alias snd-card-0 snd-als4000 # I2C module options alias char-major-89 i2c-dev options snd-card-0 index=0 options snd-als4000 index=0 remove snd-als4000 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-als4000 options lockd nlm_udpport=4001 nlm_tcpport=4001 -------------------------------------------------- * asound.conf is as follows: -------------------------------------------------- #Generated by system-config-soundcard #If you edit this file, don't run system-config-soundcard, #all your changes here could be lost. #SWCONF #DEV 0 defaults.pcm.card 0 defaults.pcm.device 0 defaults.ctl.card 0 -------------------------------------------------- There is no asound.conf under FC6. There is an asound.state, however. * The Gnome volume control complains: "No volume control GStreamer plugins and/or devices found." * Alsamixer complains: -------------------------------------------------- [root@charlesc etc]# alsamixer alsamixer: function snd_ctl_open failed for default: No such device -------------------------------------------------- * Possibly significant are the three sets of messages in dmesg like so: -------------------------------------------------- ACPI: PCI Interrupt 0000:00:0a.0[A] -> GSI 16 (level, low) -> IRQ 18 architecture does not support 24bit PCI busmaster DMA ACPI: PCI interrupt for device 0000:00:0a.0 disabled -------------------------------------------------- as they appear to refer to the sound card: -------------------------------------------------- [root@charlesc ~]# lspci | grep -i audio 00:0a.0 Multimedia audio controller: Avance Logic Inc. ALS4000 Audio Chipset -------------------------------------------------- Expected results: Sound works, a working configuration is constructed. Additional info: This card worked under FC6. I have those configuration files should you need them.

It's a problem in drivers. You can check the new drivers (how-to is here - http://people.redhat.com/stransky/alsa/) and if it doesn't help, please report it to upstream (www.alsa-project.org) and attach the logs there.
It's a driver problem, alright, but not what you thought. I was running a xen kernel, 2.6.20-2925.11.fc7xen, at th time I reported this. I rebooted to the current non-xen kernel (2.6.21-1.3228.fc7), and the problem went away. I did not install the new drivers. I have not tried setting up a virtual machine yet, so I can't tell you if the drivers, new or current, work correctly in one.
aha, okay. so it's a problem in the xen kernel. moved to kernel component.
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest xen kernel? I'm re-assigning to the xen kernel team and they may wish add comment. If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris
Since then, due in part to this and in part to the fact that the Radeon drivers don't support the xen kernel, I have removed xen from this machine. This machine is also my desktop, and I have to have sound and fast graphics for work. Either one is a show stopper for me. I've given up on xen until such time as I can do everything else I need to do and run virtual machines. If this is important enough, I can take some time and fiddle with it. But I don't need it until Radeon supports the xen kernel.
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. Fedora 7 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
