Hi Everyone,

I thought I’d try some Creative T-100 Bluetooth speakers with one of my Max2Play Pi4,1Gb & HifiBerry Amp2 bundles. Using m2p_buster_rpi-v253.img

Installed everything as normal and updated all the packages and then scanned my media library from an attached USB3 drive.

Installed the Bluetooth addon and it sees and connects to the speakers. Debug output is:

Then changed the Audiocard advanced settings to select as my soundcard ‚Bluetooth – Your Bluetooth device 30:21:76:B8:CF:81,
Edited the command line options to -o hw:1 -V Digital -B

Stopped Shairport running and unticked ‚autostart‘.

Scratching my head as to why I can’t hear any audio from the device through the Bluetooth speakers as everything suggests that they’re connected. If anyone can offer any advice or suggestions to try I’d much appreciate it.

Many thanks.

Hi Lomcovaks,

Since you are not using a sound card via Squeezelite, you do not need the entry -o hw:1 -V Digital in the command line options. Does the audio output work without these parameters?

Dear Mario,

Thank you very much for your prompt response and clarification.

I can confirm that everything is working now.

I was slightly confused with the instructions on the Bluetooth plugin page that says

‚Important: When using Squeezelite with Bluetooth Speakers remove ‚-C 5‘ Parameter from Commandline Options and add ‚-B‘ to sychronize Squeezelite with the Bluetooth Speaker connection (On/Off).‘

I took this to mean leave the rest of the options that appeared on the command line options, not understanding that I should remove everything but I understand now.

Many thanks,

Chris
