I was thinking that some values of this register could break the audio input. It does not seem so. It looks like this webcam has not been working properly since Ubuntu Hardy. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/280657 I'm not sure of the version included in Hardy. Would it help if I tried to find the GSPCA version from Hardy to compare the changes? In searching for details on this webcam model, I came across some patches that you submitted a while back that initialize the GPIO with different values. I tested those, but saw no results. I see you've worked on this specific driver quiet a bit in the past: http://linuxtv.org/hg/~hgoede/gspca/rev/65247a979498 Is the previous maintainer, Michel Xhaard, still working on this driver at all? I wonder if he might be able to help identify the problem or narrow it down. Which function is called when I open Cheese or other video applications? Initializing the webcam appears to be correct, however, sd_start() or the one that starts the video capture appears to be toggling or changing some setting. If I knew of a way, I would insert more debug messages to help pinpoint the place where the microphone breaks along with some boolean to show that its working or not.

Fine job! The register 02 is the GPIO register. It seems the audio does

Thank you for your help. I've gotten this working for me by using the
following conditional to determine if the driver should run the code
that changes register 02 or not.
if (sd-sensor != SENSOR_OV7660)
reg_w1(gspca_dev, 0x02, 0x62);
and
if (sd-sensor != SENSOR_OV7660) {
reg_w1(gspca_dev, 0x02, reg2);
reg_w1(gspca_dev, 0x02, reg2);
}
These do fix the audio problem, but they may not be good for other
Sensor OV7660 devices. I am not sure how to identify only my model
here, but that may be ideal for a better patch. I wonder if this patch
would also be needed for the VX-3000 model?
I've attached the patch that I'm using. I attached the diff -c and
diff -uNr style patches. the uNr style looks more like the
changesets I've found at LinuxTV.org so it may be the easiest to
apply. I hope the patch helps!
Hopefully this will make it into the Kernel source before too long so
it works on other computers without modification. :D
Cheers.

I can verify that GSPCA 2.9.52 does indeed work with VX-1000. How long does it take typically for these changes to work their way into the Kernel? I'd love to see this included in the Kernel by the time Ubuntu 10.10 is released so I can stop tweaking webcam settings. On a different note, I've noticed that there is a bug either with Cheese or with the camera drivers after recording video. The problem is that, after I record a video in Cheese, the recording stops and the video is saved, but the record button is now disabled until I reopen the application. I'm curious why this would happen, but I think that more people would notice this bug if it were a Cheese bug. I'm wondering if there is something that isn't transferred or set correctly after ending the video/audio data transfers. Cheese is working with V4L2 well in all other aspects. I have been testing with Ubuntu 10.10, so I will install your latest drivers in Ubuntu 10.04 (stable) to see what happens. I know that on my laptop in Ubuntu 10.04 (where video worked, but audio didn't), the video would save and the button is re-enabled correctly. I'll test this against your latest release to see what happens since Ubuntu 10.04 installs GSPCA 2.7.0 by default. I will let you know of the results soon. And one more question. Is there anyway to give the camera button an action when the camera is not on? In windows, pressing the button would launch a predefined application (Windows Live Messenger), but I would like to write in the ability to open either a buddy list or Cheese or something relevant from the button if possible.

Microsoft VX-1000 Microphone Drivers Crash in x86_64
I'm testing the VX-1000 model web cam in test builds of Ubuntu 10.10 x86_64 and have found that the gspca drivers allow the microphone to work with a sound recorder initially. However, when I test sound and video together with Cheese, the microphone no longer works and doesn't work again on the computer until the web cam is detached and reattached.

The problem is in the main gspca.c, not in sonixj.c. It may fixed using a lower alternate setting. To check it, you may add the following lines: if (dev-config-desc.bNumInterfaces != 1) gspca_dev-nbalt -= 1; after gspca_dev-nbalt = intf-num_altsetting; in the function gspca_dev_probe() of gspca.c.

I've edited the gspca.c file with your suggestion to begin testing, but I'm unable to get the new drivers to compile with and Error 2.

If I understood more of how everything works then I'd start the bandwidth calculation progress myself. Unfortunately I don't, but I may be able to get a patch working if this will ever compile.

I don't see anything but the GPIO. I was considering adding more code to print out more detailed IO information. I have no ms-win trace from your webcam. May you do it? I just need the connection and one second of streaming with a USB sniffer in text mode as sniffbin. I tried using a couple of USB sniffers in Windows 7, but I'm unable to find one that has an option to save in text mode as sniffbin. Apologies in advanced for the length of the log files that I managed to capture. I captured the device connection, video capture start and stop, then device removed. The capture start took a moment to begin since the application loaded more slowly with usb capturing in progress. --- I tried using the open source SnoopyPro under Windows 7 and I'm not sure how well it works normally, but I was unable to capture any usb traffic in Win7. If you have any other suggestions let me know, because I've never used a usb sniffer before. I connected my webcam to a Windows XP laptop and was able to get it to capture (Windows XP laptop is 32-bit, Windows7/Ubuntu 10.10 desktop is 64-bit...which is what I am working to get the webcam working on). http://sourceforge.net/projects/usbsnoop/ In the USB Devices list I see my camera listed 3 times: USB\VID_045EPID_00F7REV_0101MI_00,USB\VID_045EPID_00F7MI_00 USB\VID_045EPID_00F7REV_0101MI_01,USB\VID_045EPID_00F7MI_01 USB\VID_045EPID_00F7REV_0101,USB\VID_045EPID_00F7 Log file from SnoopyPro: http://bit.ly/bNJiLu --- I also installed a free usb sniffer called Simple USB Logger that seemed to do a very good job and I captured data from the point that the camera was plugged into usb, then start capture, end capture and unplugged from usb. So it should be a large bit of the data you will need. http://www.all-freeware.com/download/67384/simple-usb-logger.html Log file from Simple USB Logger: http://bit.ly/92ipQ8 --- I hope these help and are what you were looking for. Let me know if you needed something different or if there is more information I can send to you. I've saved the exact program versions in case you have trouble getting them for any reason and would like to look into them: SnoopyPro: http://bit.ly/bX6r9r Simple USB Logger: http://bit.ly/bshLuz Thanks. -- Kyle Baker -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
