I did some updates:
-- redid everything into a single script run at startup and on
squeezelite power on, actions dependent on current track title
-- got rid of the three separate json queries. Finally figured out how
to do it once and assign to a variable, just need a space after the
opening $(
-- simplified the json query to just get current song title, previously
I recycled a query from another thread which had a bunch of tags I
didn't need for this
-- had to add back in some buffer settings into /etc/asound.conf (I'd
removed them completely) because bluealsa-aplay dies without them.
-- I tried a few different alsa utils to see if I could programmatically
determine the delay between the onboard audio and bluetooth speaker but
failed. Have added a manual sync method where every time you toggle the
power on squeezelite it increases the latency to the onboard audio. You
just keep doing it until it sounds right.
-- got rid of a useless use of cat
I've tested everything again and it's all working well. I paired my
headphones, my phone, and my wife's phone and was able to play prime
music from my phone, youtube audio from my wife's phone, music from
squeezelite all at the same time streamed to my bluetooth headset
synchronized with the onboard audio. Not that you'd ever want to do
that, but it worked.
Next I need to see if I can determine and then send sync settings to LMS
so the squeezelite player on this box is in sync with the rest of the
players in the house, currently it is not, because of the various buffer
settings.
