Hi there, I've got fairly big issues with my Windows 10 install lately (despite being on the insider preview for 8 months and it working fine....which is annoying). This matches similar issues on the forum (should I have replied there instead of here? Sorry
it wasn't fully clear and some places separate each person into their own thread):
I have a laptop that has integrated (Intel HD Graphics 4600) and discrete (Nvidia Geforce GTX970M) graphics. Up until the past few days (not sure when exactly as the problem is hit and miss until yesterday, when it fully stopped).
When I hook my laptop up to the TV via HDMI, after it correctly setups up the displays and detects the TV in the sound playback settings:
- No sound will come through 99.9% the TV speakers, despite it showing in Sound, being set as the default device and the green bar showing activity.
- However, very occasionally, I can hear an audible click when I start to play something as if it's connecting. Very rarely (like, once), I managed to get 5 seconds of audio.
- When the HDMI is set as the default playback, video (in particular, hardware accelerated video, I'm presuming) will playback very choppily. If internal speakers are set, it's fine.
I have tried both the latest graphics version from Intel (220.127.116.11.4256) and the one via Windows Update (10.18.15.4256) after uninstalling the latest one. Unlike one of the other threads, neither of these worked. Unfortunately, Intel do not offer any other Windows 10 drivers and I cannot install any for Windows 8.1.
I have also tried running the sound troubleshooter, which only told me to set a default. Ended up setting my internal speakers again. Useless.
I have verified the hardware works just fine by running a quick speaker-test in an Ubuntu live CD. The internal speakers also work just fine.
All in all, I don't think there's anything I can do unless anyone has any suggestions? Please fix these drivers ASAP.
