New USB Headset - Looks Good, No Audio


Hi -

I recently installed (a.k.a "plugged in") a new Plantronics .Audio 910 Headset. Upon restarting the machine, dmesg reveals the following:

Code:
usb 2-1: new full speed USB device using ohci_hcd and address 2
usb 2-1: configuration #1 chosen from 1 choice
input: Plantronics Plantronics BT Adapter as /class/input/input2
input,hiddev96: USB HID v1.11 Device [Plantronics Plantronics BT Adapter] on usb-0000:00:03.1-1
This is what happens when I open Skype (running as root to prevent permissions issues):

The sound is fine through the built-in soundcard. Everything can be heard properly.

When the sound device is changed to the "Plantronics BT Adapter", however, the test call gives an error message -- "Problem with sound device".

Also, when opening alsamixer -c 1 to see if there are settings to be changed on the adapter, there are two options available: PCM - which is set to "53" and cannot be changed; and Mic - which is set to "0" and cannot be changed.

Same situation in kmix.

What is happening here? Any ideas?

Thanks in advance.

There is a kernel module called snd-usb-audio, which provides the drivers for USB sound systems in linux. Check the output of command 'lsmod' to see if this is already loaded.

Otherwise you could try loading this manually (as root from the console command line) with command 'modprobe snd-usb-audio'. Then check alsamixer for any further functionality.

From the messages you post I see the device has already been claimed by the USB HID (human interface device) driver. I'm not sure if this is significant or not.

What linux distribution are you using? One with good hardware support shoud be able to figure out what drivers to load.

You should not have to reboot after plugging in a USB device. You might get more information by running 'tail -f /var/log/messages', plugging the headset into the running machine and checking the output.

Hi maroon, thanks for your response.

I just upgraded to F7, and it works perfectly.

Thanks anyway. At least I will know to ask questions here rather than
waste time posting to the forums at skype.com...
