Logitech USB headset not recognized for Pulseaudio
Last modified: 2018-04-11 03:02:23 EDT
Description of problem: When my Logitech USB headset is inserted into computer, it is not recognized by Pulseaudio. However, it is found in lshal output, although not as an audio device. Version-Release number of selected component (if applicable): hal-0.5.11-1.fc9.i386 pulseaudio-0.9.10-1.fc9.i386 alsa-lib-1.0.16-3.fc9.i386 Linux viklef 2.6.25.4-30.fc9.i686 #1 SMP Wed May 21 18:12:35 EDT 2008 i686 i686 i386 GNU/Linux How reproducible: 100% Steps to Reproduce: 1.insert USB headset into USB slot 2. 3. Actual results: Pulseaudio doesn't recognize it as audio device Expected results: it should Additional info: There might be something about my USB ports, because apparently one of them doesn't work at all -- lshal doesn't see anything there. But in the other it does, and it did work just in the morning.

Did you reboot into a different kernel since this morning? Can you try this on an older kernel and if it works figure out what kernel package caused this?
OTOH, there's | | |-- card1 -> ../../devices/pci0000:00/0000:00:1d.0/usb5/5-1/5-1:1.0/sound/card1 and I think user space (e.g. HAL) can deal with this. However, that appears to be a broken symlink (according to 'tree /sys' output). Matej, can you paste the output of /sys/devices/pci0000:00/0000:00:1d.0/usb5/5-1/5-1:1.0/sound/card1 Thanks.

This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '9'. 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 9'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 9 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 to the applicable version. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
