Created attachment 441551 [details] Contents of /proc/asound/card0/codec#0 with options snd-hda-intel model=dell-s14 Description of problem: The internal microphone on the Dell E6510 does not work. I have adjusted the mixer levers and ensured that the capture device is not muted. When attempting to record an audio file, no sound is captured. Version-Release number of selected component (if applicable): kernel: 2.6.33.8-149.fc13.x86_64 alsa-plugins-pulseaudio-1.0.22-1.fc13.x86_64 report-plugin-localsave-0.14-1.fc13.x86_64 alsa-lib-1.0.23-1.fc13.x86_64 alsa-utils-1.0.23-3.fc13.x86_64 alsa-firmware-1.0.23-1.fc13.noarch alsa-lib-devel-1.0.23-1.fc13.x86_64 alsa-plugins-pulseaudio-1.0.22-1.fc13.i686 alsa-tools-firmware-1.0.23-1.fc13.x86_64 report-config-localsave-0.14-1.fc13.x86_64 alsa-lib-1.0.23-1.fc13.i686 How reproducible: Always Steps to Reproduce: 1. Turn on computer with an IDT 92HD81B1C5 Intel HD audio device (e.g. Dell E6510) 2. View mixer levels and verify that capture devices are not muted 3. Attempt to record a sound file using (e.g. using audacity) Actual results: No sound is recorded Expected results: The sound picked up by the microphone is recorded Additional info: The microphone can be made to work by adding the following line to a modprobe.conf file: options snd-hda-intel model=dell-s14 With this option set, the microphone works as expected and sound can be recorded. $ lspci -vvv 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) Subsystem: Dell Device 040b Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 32 Region 0: Memory at e9660000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel 01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1) Subsystem: Dell Device 040b Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 16 Region 0: Memory at e3080000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel
Problem still exists with kernel 2.6.34.6-47.fc13.x86_64
Confirming that by adding the following line: options snd-hda-intel model=dell-s14 to /etc/modprobe.d/dist-alsa.conf fixes the issue completely for me as well. Running kernel 2.6.34.7-61.fc13.x86_64
Duplicate of bug 616197. Confirming this problem still exists on Fedora 14 and the solution from comment #2 is correct!
I can't reproduce the problem in F15 beta.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. 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 '13'. 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 13'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 13 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
Confirming that this issue is no longer present in the Fedora 15 Final release. This bug can be closed.
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
