Might be a question for Philips I would say: who do you expect to write the driver? For Windows everybody expects the vendor to create / ship them. For Linux everybody expects them 'just to work' (seems nobody has to write them, let alone having specifications on how to interact with the hardware).

Hi Dominique, I agree on you points, however, them cannot be used as a mere justification simply because it wouldn't be the first case where the vendor has not wrote a specific driver for Linux but despite of this, the hardware doesn't works. Linux is great and is powerful also because it can do more and better of M$ normally for free, but there are still some points where it lacks against Windows and USB Microphone is one of these. I think that present issue is not just on Philips brand; I guess other users, with different USB WebCams with integrated Mics suffer of same problem on video or audio or both failure and this is not IMHO so much justifiable.

There is a USB Audio Class which is implemented in Linux ... Isnt it used in that device?

lsusb -v output of it?

Ciao, Marcus

The worst part is that "apparently" everything works: ie modules and usb devices corretly revealed by kernel. uvcvideo is loaded and camera works correctly! snd_usb_audio is loaded but no audio out! Note: If I firstly boot on Windows, then reboot on openSUSE 11.2, letting camera plugged, then audio works, but voice is sampled at bigger speed, appearing as Walt Disney Mickey Mouse original voice!

That behaviour heavily reminds me of any other device that is loading a firmware in the device when booting into Windows (WiFi for example), keeping the firmware there until you unplug it. Did you ever check what dmesg tells you when you connect this device?

Dominique

I can provide my latest dmesg output at first occasion. BTW, as I stated, it seems that apparently all is correctly recognized. TKS, Marco -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Go to the Linux uvcvideo homepage, look at the supported UVC webcams and try one of these:

This is what I will do. I will give away my SPC620NC and go maybe for a Logitech.

I use Logitech Quickcam Pro 9000 with built-in microphone. Webcam and built-in microphone all working great.

regards,

Thanks for your testimonial. I already bought two webcam so far: the first one with just the video section and the second one with both audio and video. The first one was not working at all on Linux (this is not a uvcvideo class but a sn9c20 family web-cam). The second one works only on video. Now, before spending more money to buy a new product, I'll wait a while, to see if something happens.

Waiting for.... ??

The *moral* here is, investigate the availability/work-a-bility in linux for the device before purchasing. You wouldn't purchase a metric bolt for an sae nut...

Waiting for a new kernel, HAL, udev, ... Or something else, which manages such device, without the need to have to purchase a brand new. I think to have investigated enough, searching on HW compatibility lists and also attempted several workaround suggestions for the specific issue, without any success. Last but not least: I've not yet found a Computer shop which accepts you try the peripheral before purchasing... If you know such one here in Brazil, please let me know ;-) Marco -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi there,

I have a Philips SPC620NC and I have the same audio issues, it is virtually impossible to get the built in microhphone running. I currently use a headset connected to my soundcard and use the webcam for video only. I can only recommend, take your fingers away from Philips webcams.

Go to the Linux uvcvideo homepage, look at the supported UVC webcams and try one of these:

http://linux-uvc.berlios.de/#devices

This is what I will do. I will give away my SPC620NC and go maybe for a Logitech.

By the way, this is not Linux' fault. It also depends on the hardware make to give information to write proper drivers, if the hardware make is not helpful, the community cannot do much.

Regards Malte

Generally that's because the Logitech cams support the UVC standard...I have a Logitech 250 and all I did was plug it in.. and it works. I didn't have to do anything at all to get it working. Previously, I had a Philips cam... and getting it to even start up was a nightmare let alone getting the microphone working (something I've never managed).

After following this thread, i got a Logitech Portable Webcam C905, which is listed as working with Linux. I plugged it in, and I get this: [ 1105.817046] usb 1-5: new high speed USB device using ehci_hcd and address 7 [ 1106.159372] usb 1-5: New USB device found, idVendor=046d, idProduct=080a [ 1106.159399] usb 1-5: New USB device strings: Mfr=0, Product=0, SerialNumber=2 [ 1106.159417] usb 1-5: SerialNumber: 52A9A160 [ 1106.159664] usb 1-5: configuration #1 chosen from 1 choice [ 1106.160651] uvcvideo: Found UVC 1.00 device <unnamed> (046d:080a) [ 1106.200358] input: UVC Camera (046d:080a) as /devices/pci0000:00/0000:00:1d.7/usb1/1-5/1-5:1.0/input/input12 which seems good. I am a member of the video group. The device shows up as: crw-rw----+ 1 root video 81, 1 2010-04-05 09:52 /dev/video1 Before I can access the camera in Skype, I first have to run kopete. I wonder why that would be. Flash does not seem to be able to detect the camera. I have gone through the settings to be sure the sites should ask before accessing the camera. The Flash app simply says "Detecting camera" and never shows the Allow dialog. I really hate flash... But I want to get this to work.

Since then I have found this site:

http://oldes.multimedia.cz/swf/mx-webcam.html

And the camera works. So, it is something in the specific flash app that is causing the problem. This test is older. Maybe there is a newer flash webcam API that the flash app is using that has the issue...

I first have to run kopete and set the camera properties. I use the "Default" button which makes the settings (camera, image settings) the new defaults.Then flash is happy. Without this step, access to the webcam fails. It seems it survives boots. So, problem solved. It is "plug it in", "fiddle a tiny bit", then "it just works".
