I updated to Ubuntu 15.04 from Ubuntu 14.10 a few days ago, and now my Logitech G230 headphones don't receive any sound. How can I fix this? PulseAudio Volume Control detects my headphones, and says they're working, but no sound comes through.
EDIT: Using alsamixer
worked at first, but now it doesn't, and I get frequent bursts of static through my headphones now.
