No, as 1.4.7 Low or No Background Audio (AAA) isn't about parallel but
separate audio sources.

The fact it double-announces the time is a bit unfortunate and could do
with being looked into (likely a combination of a live region and the
announcement of the actual slider value itself). However, having this
announcement will be essential for SR users, so a difficult circle to
square.

Anecdotally, screen reader users are very good at
isolating/distinguishing different sound streams, even concurrent ones
(within reason, of course).

If it proves too noisy/competing, users can also pause the video first
before scrubbing.
