[arch-general] usb webcam no audio
I haven't been able to get audio on my webcam for a while. My initial guess is that it has to do with all of the udev changes. I'm using gnome w/ pulseaudio. The audio properties show the device on the input tab, but it doesn't detect any activity. everything.log: Jul 21 23:54:08 newguy kernel: [11606.472285] usb 4-5: new high speed USB device number 2 using ehci_hcd Jul 21 23:54:09 newguy mtp-probe: checking bus 4, device 2: "/sys/devices/pci0000:00/0000:00:13.2/usb4/4-5" Jul 21 23:54:09 newguy mtp-probe: bus: 4, device: 2 was not an MTP device Jul 21 23:54:09 newguy kernel: [11607.089065] Linux media interface: v0.10 Jul 21 23:54:09 newguy kernel: [11607.121723] Linux video capture interface: v2.00 Jul 21 23:54:09 newguy kernel: [11607.129054] uvcvideo: Found UVC 1.00 device Hercules Dualpix Exchange (06f8:3005) Jul 21 23:54:09 newguy kernel: [11607.134791] input: Hercules Dualpix Exchange as /devices/pci0000:00/0000:00:13.2/usb4/4-5/4-5:1.0/input/input6 Jul 21 23:54:09 newguy kernel: [11607.134938] usbcore: registered new interface driver uvcvideo Jul 21 23:54:09 newguy kernel: [11607.134943] USB Video Class driver (v1.0.0) Jul 21 23:54:09 newguy kernel: [11607.197743] 2:3:1: cannot get freq at ep 0x84 Jul 21 23:54:09 newguy kernel: [11607.198679] usbcore: registered new interface driver snd-usb-audio Jul 21 23:54:09 newguy kernel: [11607.251849] 2:3:1: cannot get freq at ep 0x84 Jul 21 23:54:09 newguy kernel: [11607.276979] 2:3:1: cannot get freq at ep 0x84 Jul 22 03:54:09 newguy rtkit-daemon[1012]: Recovering from system lockup, not allowing further RT threads.

what is in your `Configuration` tab after running `pavucontrol`? i had trouble getting sound working consistently until i realized i had that on the wrong device ... even though it seemed like the "right" choice. C anthony

I have: RS880 Audio Device [Radion HD 4200] Digital Stereo (HDMI) Output Hercules Dualpix Exchange Analog Mono Input Internal Audio Off when I turn the input volume all the way up in both places, I think I can hear something slightly. If I do a Skype test call I hear a lot of white noise and some faint tapping if I hit the webcam. I suppose it's possible that it's actually using the wrong device somehow, but there are no other mic's that I know of on this desktop =/ I don't think there's one built in to the HDMI monitor.

hmm yeah i don't know a whole lot about it :-( after enough tinkering i just got my to work finally and never looked back ... mine had lots and lots of "profiles" for each device, of which only 1 or 2 worked correctly (mainly because i didn't have the equipment to support the others, eg. 5.1/7.1/etc) only other thing i could suggest, and maybe you already did this, but make sure your devices aren't muted in `pavucontrol`, have volume (== input sensitivity for mic IIRC), and make sure appropriate devices are flagged as the default/fallback -- this is all in `pavucontrol`.

Hmm, it may or may not be related, but downgrading to 2.6.38 certainly solved the problem. I'll continue the discussion of the forum. Thanks!
