ActivBoard sound problem
We have several Promethan ActiveBoard 387 Pros and recently the sound started lagging when watching a video on the internet or listening music etc... It's sorta like an android sound or some sort.
I updated the firmware version on all of them, which is fixed the problem but just for a short while. I reinstalled the driver and the software with no luck. We have Windows 8.1 on all laptops. This issue is totally random, and the activinspire program is always runs fine, just the sound starts to lag.
Can You help me with this problem?
