I would recommend just keeping it simple. Two buttons: one for captions,
the other for mute. This gives the user the greatest control and the
most options.

To extend what Sean said, I would think that having to press "Mute" to
activate CC would qualify as "a surprise to the user." At least I would
think most users would not expect "Mute" to mean "Turn on CC."

Becky,

Re: #1. I'd go with the standard practice of leaving the audio rolling
even when captions are activated. Hearing/Deaf is not a binary
opposition in which people who are hearing can't benefit from captions
and people who are d/Deaf can't benefit from audio. Instead, there are a
range of subject positions with varying preferences and needs: hearing,
audiologically deaf (with varying degrees from profound to severe
hearing loss), hard-of-hearing (with varying degrees from mild to
moderate hearing loss), Culturally Deaf (i.e. but also able to pass for
hearing).

Just as we double up when color is involved (Ensure that all information
conveyed with color is also available without color -- WCAG 1.0,
Guideline 2.1 & Section 508, section 1194.22c), we should do the same
for captions (i.e. captions are available together with audio, rather
than each on its own).

Re: #2. Whatever you do, it should not be a surprise to the user (like a
pop-up window that a screen reader user doesn't know about).
