Steps to reproduce the problem:
1. Play any audio over Bluetooth from Chromebook. Issue is especially noticeable with music.

What is the expected behavior?
Music should play with a wider dynamic range, as it did prior to OS updates

What went wrong?
Music lacks all treble range. Recordings sound like they're being played from a victrola from the 1930s. The audio also repeatedly drops out intermittently for a split second.  When connected via audio cable, the sound plays normally. This bluetooth audio issue has not been replicated on any other device (OS's on those devices: Mac OSX 10.11.5,  Android 5.0 [one with build LRX21V.N900TUVUFOL1, the other phone's build unknown], and an old phone running Cyanogen v10.1/Android v4.2.2)

Did this work before? Yes Winter 2015/2016 was the last time I successfully used the speaker with the Chromebook

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? N/A 

Chrome version: 50.0.2661.94  Channel: stable
OS Version: 50.0.2661.94
Flash Version: Unknown, integrated with Chrome OS

I have not used the bluetooth speaker (Jawbone Mini Jambox) with this specific computer in several months, so I'm not sure which OS update may have contributed to the bug. Bluetooth has always been buggy on my Chromebook Flip (refuses to pair, no troubleshooting steps work). I attempted to test various audio sources to see if there was a difference in the audio output, but am unable to due to the unreliability of the Bluetooth hardware/software. Gave up after 15 minutes of trying to pair. Very unhappy with Bluetooth performance on this thing. Not sure of the pairing issue is an Acer issue, a Chrome OS problem, or both. The low fidelity audio issue definitely appears specific to Chrome OS, however.

I can't test in other browsers because Chrome is the only browser available on Chrome OS.
