My right speaker sounds muffled.
my right speaker is muffled sounding. this goes away when I change the format on audio MIDI setup or when I plug and unplug headphones, but comes back soon after. it is also triggered by turning the volume up to maximum and then the speaker goes muffled sounding and I have to reply and unplug headphones to get it back to normal. How do I I fix this?
