I have the same problem on x86_64 F13 with a Creative Live! Cam Optia Pro VF0380 webcam. On rare occasions the microphone works, then upon rebooting it fails to work again. However, it is detected consistently. Alsamixer says "This sound device does not have any playback controls.". usb 1-4: new high speed USB device using ehci_hcd and address 5 usb 1-4: New USB device found, idVendor=041e, idProduct=4065 usb 1-4: New USB device strings: Mfr=2, Product=1, SerialNumber=3 usb 1-4: Product: VF0380 Live!

Both F12 and F13 were clean installs.

Reassigning to kernel. 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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 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 Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Description of problem: The UVC webcam Philips SPC530NC's embedded microphone does not work. The kernel recognize it correctly as USB device and also Gnome Audio allows to select it as input microphone, but audio recording fails and mic level remains static. Video works without any issues. Version-Release number of selected component (if applicable): Fedora 13 x86_64 How reproducible: Always. Steps to Reproduce: 1. Plug the webcam into the USB, 2. Try recording audio, 3. No sound is recorded. Actual results: The embedded USB microphone stays mute. Expected results: The embedded webcam microphone should work. Additional info: Trying to record with: arecord -Dplughw:1 -fdat -vv foo.wav Returns a 44 bytes file without any audio and no error, as bellow. $ arecord -Dplughw:1 -fdat -vv foo.wav Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Plug PCM: Route conversion PCM (sformat=S16_LE) Transformation table: 0 <- 0 1 <- 0 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 24000 period_size : 6000 period_time : 125000 tstamp_mode : NONE period_step : 1 avail_min : 6000 period_event : 0 start_threshold : 1 stop_threshold : 24000 silence_threshold: 0 silence_size : 0 boundary : 6755399441055744000 Slave: Hardware PCM card 1 'USB Video Camera' device 0 subdevice 0 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 1 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 24000 period_size : 6000 period_time : 125000 tstamp_mode : NONE period_step : 1 avail_min : 6000 period_event : 0 start_threshold : 1 stop_threshold : 24000 silence_threshold: 0 silence_size : 0 boundary : 6755399441055744000 appl_ptr : 0 hw_ptr : 0 dmesg output after plugging the webcam: usb 1-3: new high speed USB device using ehci_hcd and address 11 usb 1-3: New USB device found, idVendor=0471, idProduct=2034 usb 1-3: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 1-3: Product: USB Video Camera uvcvideo: Found UVC 1.00 device USB Video Camera (0471:2034) input: USB Video Camera as /devices/pci0000:00/0000:00:1a.7/usb1/1-3/1-3:1.0/input/input19
