Description of problem: internal microphone volume of my Lenovo Thinkpad T400 is set to 0 by default (not muted however) and cannot be controlled from a user interface. Version-Release number of selected component (if applicable): pulseaudio-0.9.22-5 Steps to Reproduce: 1. Start gnome 3 2. Try to use internal microphone in any way (or look at the input level in gnome sound settings) Actual results: Microphone does not record any sound since its volume is set to 0. There is not way in gnome to control that volume. The internal microphone does not appear anywhere in the gnome dialogs, and 'pavucontrol' either. Expected results: Users can run Skype or similar and use the internal microphone. Additional info: alsamixer -c0 reports 3 items in the category "Capture" (viewed by pressing F4). "Mic", "Docking Mic", "Internal Mic". When I increase the volumne of "Internal Microphone", I am able to use the microphone. However, after system restarts the volume is reset again...
Note that this is a regression from Fedora 13 (I have not tested it with Fedora 14).
I just noticed there is an error when manually starting pulseaudio, maybe this helps: $ pulseaudio E: module-alsa-card.c: Failed to find a working profile. E: module.c: Failed to load module "module-alsa-card" (argument: "device_id="29" name="platform-thinkpad_acpi" card_name="alsa_card.platform-thinkpad_acpi" tsched=yes ignore_dB=no card_properties="module-udev-detect.discovered=1""): initialization failed. I think it starts anyway and reverts to some (wrong?) defaults, as witnessed by $ pacmd list-modules ... name: <module-alsa-card> argument: <device_id="0" name="pci-0000_00_1b.0" card_name="alsa_card.pci-0000_00_1b.0" tsched=yes ignore_dB=no card_properties="module-udev-detect.discovered=1"> used: 1 load once: no ...
I have this issue on Fedora 16 with kernel 3.2-rc3 and pulseaudio-0.9.23-1.fc16.x86_64 on Lenovo T520i. The difference from the description is that my internal mic is muted. If i unmute it from alsamixer, i have capture in the sound settings gui. Pressing mute/unmute in the Settings/Sound/Input controls the Mic in alsamixer. I am using the "Analog Stereo Duplex" profile. I used preupgrade from Fedora 15 to 16. In 15 internal mic was working correctly.
The same happens on Fedora 16. Kernel 3.1.6-1.fc16.x86_64. Each time the system reboots the internal mic volume is set to 0. This is a clean install of Fedora KDE spin.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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
