You should back up your data, properly! If you’re not, you’re playing a dangerous game with fate. Computers are pretty reliable, but they also go wrong, often. You should always backup your files, but backing up a containerized application isn’t quite as simple. A container is 3 things:ConfigurationVolumesNetworking The point…
Bluetooth audio is great! I’ve had a pair of Bluetooth headphones, Sony MDR-XB950 BT, for around a year now, and the ability to listen to music without cables is amazing. But, I can only use the Bluetooth parts of this with my phone, because on Linux, it just sounds terrible. I’ve even gone so far as to buy and wire in a cable on my desk at work to enable me to fairly easily connect to my desk, without having to plug into the desktop every day.
The issue is caused by a lack of
A2DP, a Bluetooth profile for transmitting stereo audio at high quality. According to the manual for my headphones, it supports
A2DP just fine, however, my computer was reporting it didn’t, and so was saying it was unavailable.
After a large amount of searching, I came across a number of solutions, none of which worked. From trying some alternative software, to modifying config for
bluetoothd, no change.
