I have Logitech wireless USB headphones. I have the system recognizing the headphones and I can play the test music clip in the sound setup under YAST. The problem is how do I get the application to recognize the headphones. YAST shows three sound cards as follows
0 - Logitech USB headphones (this is set as default)
1 - A HMDI port on the ATI card
2 - SBx00 Azalia
the driver for the Logitech headphones is snb-usb-audio
When I try to play a wav file using Amarok or VLC there is no option for the headphones even if I try to configure the backend which BTW resets as soon as I apply and exit. The headphones also do not appear in Kmixer.
I think that the OP USB headphone maybe work just like a usb speaker.
I have a bose usb speaker and I made it as the primary sound in yast
enable the simultaneous sound in paprefs and use pavucontrol and xfce4-mixer
to configure the sound output device and playback.
