I can successfully connect my android device as audio source, and listen to music, youtube videos etc. on my laptop(that are played on android phone). But when I'm in a call, the audio doesn't go through the laptop, but it works on my bluetooth headset. If I select an option on my android phone to transfer the call via bluetooth(like I would on my headset), there's no sound on my computer...
What I tried:
How to set up Ubuntu PC as bluetooth headset to attend calls - Doesn't work
How can I make usual phone calls using a connected mobile phone? - seems outdated, cannot install
