I have a 13" 2015 rMBP with the latest Yosemite update. I have been a Boom and Boom 2 user for a long time with no troubles until yesterday. Repeated uninstalls, and installs, and reboots have done nothing to fix the scratchy, fuzzy, and distorted sound I get whenever I click on any audio source at all. I have to go to "Effects" and fiddle with ambiance and fidelity every time something audio begins. Very frustrating and disappointing, as Boom 2 was working great before. Is there anyone on the forum who is using Boom 2 who has encountered this issue? And if so, have you come across a fix? I have downloaded Hear for Mac and that does a great job of enhancing speaker sound on my MBP. But I'd like to have a working Boom 2 as another option too.
