I installed the 15.6 beta which isn't listed as Windows 10 compatible but it has fixed the issue with media players like Potplayer and VLC but the Movies&TV app seems to not want to play videos now.
Just manually download the Catalyst 15.7.x Drivers, although you will likely need to install the Chipset / APU Drivers first so that Catalyst will then properly recognise your hardware.
This said I would highly recommend installed Catalyst 15.6 Beta (again it can be manually accessed from the download page) for Windows 7/8.1 over 15.7 for Windows 10.
There are some extremely common issues with the new 15.20.xxxx Display Drivers that are not present in the 14.20.xxxx that are used in the older drivers.
Ignore that they say they're for older versions of Windows, as Windows 10 is 100% Compatible with Windows 7/8.1 Drivers (so if you have an install / backup Disc that your Laptop manufacturer gave you TRY THAT FIRST)
I have Asus 1215b with E-450 APU with HD6320 integrated graphics and I have the same problem with no drivers available. Latest one for HD6320 is from March so it's not prepared for Windows 10 RTM build 10240
I have the same problem my pc is
HP pavilion dv6, AMD Radeon HD 6300 series, I already install windows 10,
Is the AMD Radeon HD 6300 series supported? if yes where can I get the drivers?
GPU-Z shows my HD6320 as HD6320 so it is HD6320. When AMD re-brand old cards models they changed names to newer ones.
When I buy PC it definitely won't include AMD hadware. When I needed to mod Nvidia driver I just placed one line, one string (which contain my card) to the *.inf file and I was able to install all types of drivers: quadro, desktop and mobile.
Uninstall all catalyst software and drivers
Then download catalyst 15.6 Beta !
works like a charm on windows 10, video in Edge , Netflix app ,,,
I have a desktop e450 with hd6320
