Last year, around November, if my memory is correct, I was struggling with an issue with AudioBox. It plays well for a while and the sound of the left side of the speakers disappeared all of sudden. I tried many things to fix it, but no luck. So, I thought the AudioBox was broken. However, I found it was a problem with the driver. Since I updated the 3.4.1 version, it worked smoothly.
However, a similar issue has come back since version 3.5.0 was released. It happens to the headphone this time with the same issue before. I Hope Presonus fixes this issue permanently.
