Namely, that if I had the camera plugged in (usb) at boot time the sound on the computer did not work, if you plugged it in after boot, everything was fine.<\/p>\n<p>This was pretty irritating because if I forgot I would often have dozens of windows open and ready for work before I realised.<\/p>\n<p>Normally this happens because the cards are loaded in the wrong sequence by udev. But, if you listed the sound cards with<\/p>\n<pre class=\"lang:sh decode:true \">cat \/proc\/asound\/cards<\/pre>\n<p>the main card wasn't just in the wrong order, it simply wasn't there. I tried comparing modules loaded with and without the camera (at boot) and manually loading the differences, but this did not help. I tried forcing the index to be zero on the correct card, but this also did not help.<\/p>\n<p>In the end, I made the following edit to <em>\/etc\/modprobe.d\/alsa-base.conf<\/em><\/p>\n<pre class=\"lang:sh decode:true \"># Keep USB (webcam from being loaded as first card)\r\noptions snd_usb_audio index=-2\r\n<\/pre>\n<p>and this did the trick. So if like me you were searching for the answer to this, I hope it helps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I've had a Logitech QuickCam Pro 9000 for some time now, and it works well, but I did have one bizarre problem with it when I used it with my main desktop machine (running Debian (Sid)).
