Ports are something different. You need to set outputs.select with
mixerctl. The value 'auto' lets the firmware chose (i.e. it will
use HDMI if it detects an audio-capable device), 'hdmi' choses
the HDMI port, 'headphones' the analog output. For some devices
you also need to force the audio capability in config.txt to make
HDMI audio work.

Bluetooth is connected to an UART, not SDIO. You need to attach it
with btattach by configuring an entry in /etc/bluetooth/btattach.conf.

There is also the conflict between bluetooth and console. Both
want the "full" UART for performance (FIFO) and constant baudrate.
You have to chose between several compromises.

To some degree.

The internal "flow control" locks up. I have a crude workaround
(basically ignoring flow control and skipping the following errors).
