[Bug 1736222] [NEW] speech-dispatcher distorts all sound

[Edward]

Public bug reported:

So, a brand new computer running Ubuntu 16.04.3 LTS.
In hardinfo summary, my audio adapters are
• HDA-Intel - HDA Intel HDMI
• HDA-Intel - HDA Intel PCH
• HDA-Intel - HDA NVidia
In detail: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
Memory 16kb (non-prefetchable), snd_hda_intel

As soon as I load a website in Firefox that utilizes speech-dispatcher
(fimfiction.net) all sounds get distorted, whether I click a paragraph
for TTS reading or not. The problem seems to go away if I don't use the
site after a while. When I close down Firefox the problem still lingers
a bit, but maybe not as long. One thing I did which seemed faster was
close down everything, then load what I wanted to listen to (Skype,
Discord), and if it still persisted I would go into "Sound Settings" and
after a few blinks in that window the sound is normal again.

While the site is open, according to "Sound Settings" (from the speaker
icon menu) and Pulse Audio Volume Controller (pavu) there are 4 copies
of this package. Muting them did not help the problem, but moving one of
them, and a very specific one, from the "Built-in Audio Analog Stereo"
to something else like HDA NVidia (HDMI 3) seems to be a workaround.

Just so you know, I do not use the HDMI cable for sound, but instead use
the "headphones" jack. If you need any more details, I'll try to provide
them.
