Audio playback frequencies are distorted...
All of a sudden, audio playback through my speakers/headphone jack is muddy and distorted. Sometimes, the vocal track disappears completely. This is not just in iTunes (where I've unsuccessfully tried to adjust the equalizer), it's also on Youtube videos. Sonos, which does NOT go thru system audio, sounds fine. I'm including etrecheck diagnostics. Thanks for any ideas. Oh, and the only thing that's changed, systemwise, is the latest Yosemite upgrade. The problem started after that, but not immediately after.
