I recently just installed freya..and my logitech USB headphones seem to not work. I saw other people suggest unmuting them in alsamixer, I did that, but that did not fix anything. My speakers work just fine, does anyone have any ideas?
I had a similar problem to this, headphones didn't work automatically but they appeared in Switchboard under sound, there I could switch to them and they worked normally, try doing this first.
If it works then to make this happen automatically when you connect them open the file
/etc/pulse/default.pa as root and add the following line to the end:
Then reboot or run the command
pacmd load-module module-switch-on-connect
