Unbalanced stereo sound (left is not heard) only works with bluetooth stereo headset
The stereo sound on the left could not be heard
with both when using headphones or the built in speakers
but when I connected my mac with a bluetooth stereo headset, everything was perfect.
How do I fix this, because I have to mix some sound and I can't work with this...
Thank you.😕
