Is it possible to boost standard Mac Pro 2009 4,1>5,1 ( High Sierra 10.13.6 ) audio volume using Soundflower ?

I want to 1. increase system volume and also 2. thereby increasing output to my Bluetooth headset

I understand that Audio MIDI app needs to be configured but all volume outputs are set to full without any obvious increase in output volume.

I created a "Mulit Output Device " and assigned my headset to this. I renamed the headset to "Pink".

No success yet.

Thanks in advance

I’m not sure of a way to do this using just soundflower, but this could be done using audacity or even GarageBand. Basically, you’d set soundflower as your output in settings, open audacity, select soundflower as your input, apply gain using the volume fader, and then select your Bluetooth headphones as your output in audacity. Audacity could just run in the background with this configuration, as all system audio would be routed through audacity to your headphones, with the applied boost

Thanks for your detailed reply. I'll give your idea a try later this week. I'm frantically busy 'til then. :)
