Fix audio playback bugs due to setting speed

[ahmedre]

This patch fixes bugs due to setting the playback speed on certain
devices, even if the person does not try to change the playback speed at
all. For example, on a Pixel 8, pausing the audio and resuming causes
the playback to stop ui wise without stopping service wise due to a
silent exception from setting the playback params.

The fix here, as suggested by Claude, is not re-using the playback
params, and, instead, setting a new one, irrespective of the current
values.
