Yes, I also fixed 2 annoying issues when landing the new module:
- Wired headset/headphone should work directly from boot
- Wired heaset should also work when doing voice calls

This might be a bug in our bluez/pulse stack. Does that also happens
when connecting the same device on your desktop (ubuntu)?

Should work once we land the BT changes done by cyphermox (hopefully
later today/tomorrow).

This is expected atm.

Also expected, will take better look at this issue this week.
Thanks a lot for testing it.
