I use Bluetooth speakers on this machine. Every time the machine went to sleep I had to go to settings turn off Bluetooth and then turn them back on to get the sound back. It was annoying. Sometimes when I turned the Bluetooth back on it would acquire the external TV speakers in the front room. Again, it was annoying.
Then one day after the TV speakers had been disconnected from the TV I decided to just buy an optical cable and connect the TV speakers that way. Ever since that day I haven't had any issues with the Bluetooth speakers I use for my computer.
I was surprised by that. In fact I didn't really notice for a couple of weeks.
