i can not listen with my logitech usb headphone in amarok. is there any solution?
thanks all

Well, its probably not supported. Or you will have to configure ALSA to use your headphone as output. Amarok does not interact directly with your headphone, it's ALSA or wathever you are using as sound server.

firstly, thanks for your reply
i use fedora core5, and in fact i don't know which sound server it uses and how i can configure , if you help i will be happy...
thanks

Well, first can you answer me following questions: Did you get your headphone to work under Linux once? What are you using: KDE, GNOME or something else? Do you have a soundcard (also onboard) in your computer? If the last is the case you can open Kmix in KDE (given you are using KDE) and select your USB headphone instead of the sound card (do first check if that particular modell is supported at all). Finally you should find out what sound server you are using. I don't know for Fedora, but it's likely to be either ALSA or OSS.

i used my headphone with skype under linux. and i am using KDE. i have a soundcard. i just opened Kmix and select logitech usb headphone, but it didn't work in amarok again. i am not sure whic sound server i am using but in console i did /usr/bin/alsamixer and it opened.

Well, maybe it helps if you go to "configure Amarok" -> Output -> Output mode and there you could try to select ALSA. Then select your headphone in Kmix. If you don't use your soundcard, you could also switch it off in the BIOS or take it out of the machine, so Amarok has no other choice to use the headphones.
