Question: Does Bluetooth Output use the Audio output from the DAC Hat?

Pi-3B -> Samba -> Pi-1B  -> Bluetooth -> Speaker

This setup seems to be working well despite the limitations of the RPi 1B and my use of a generic USB Bluetooth Transmitter There are some limitations to the versatility of the RPi 1B. some of which are expected but some are rather odd. I am posting my findings here for the benefit of anybody tempted to try it

Odd Behaviour:
  • When used with moOde, the RPI 1B doesn't seen to support a USB Hub on either of its USB Ports. I had previously used Four-Port generic USB Hubs on all my RPi 1Bs running Raspbian, with anything from WiFi adapters to USB Memory sticks but none of these nor the Bluetooth adapter work with any of the Hubs.

    The symptoms are that the USB Memory sticks are not recognised and while the WiFi adapter works sometimes, the Bluetooth adapter is not recognised by moOde.

    All of these devices work perfectly when plugged into the native USB Ports on the RPi 1B
  • My Bluetooth adapter seems to always prefer pairing with the RPi 3B Bluetooth and the only way I have found to avoid this is to switch the RPi 3B off. (Disabling the RPi 3B Bluetooth in System Settings still seems to make the Bluetooth adapter pair with it. Very wierd! EDIT: Please Ignore this sentence. I had inadvertently turned off the WiFi Adapter - NOT the BT Adapter) Once paired with the Bluetooth Speaker, I can Boot up the Master RPi 3B and all works well.
  • When the USB Bluetooth adapter does work on the USB Hub, it sometimes goes "scratchy" and the sound from the Bluetooth Speaker stays distorted until the whole setup is switched off and reset and the Bluetooth adapter returned to the native RPi 1B USB Port.
What works well:
  • With the WiFi and Bluetooth adapters in the two native USB Ports, everything works perfectly:
  • I am able to Samba connect to the Master RPi 3B Library and stream over WiFi
  • Because of the limitation of the two USB Ports of the RPi 1B, I couldn't add local sticks but the one album that I put on the SD Card integrates seamlessly with the NAS Library in Tag view
  • Sound quality from the Bluetooth Speaker connected to the RPi 1B seems no different to that when connected to the BlueZ output from the RPi 3B.
