DATAPUISTOKEMISTI

Quick google search reveals hundreds of posts having exactly same problem - pairing with bluetooth audio device works but there's no audio. Hundreds of posts with incorrect instructions to fix problem. You do NOT need to uninstall random devices, restart service etc. All you need is correct Bluetooth drivers - drivers NOT available on Windows Update.

Vectorworks 2016 SP4 keeps crashing on startup with fault in module IG75ICD64.DLL when running on Lenovo W540p laptop with Nvidia Quadro 1100M. This laptop has also built-in Intel graphics and troublesome DLL is part of Intel driver package.

There's Dell drivers for Windows 10 but they fail to install. Reason is that you first need to upgrade firmware of Ericsson 3G WWAN module.

This is updated version of my original post. I purchased additional modem that's externally identical to old one but had different serial port USB ID (USB\VID_12D1&PID_1442&MI_00) missing from earlier driver pack causing original instructions to fail. I have also included latest Stick-mode firmware 21.200.07.00.805 I've found and corrected some incorrect information on original post. Modern Huawei USB LTE modems can be used in two very different modes. Default is HiLink mode where it functions as router doing NAT and other nastiness much like more traditional 4G routers connected over WLAN or Ethernet. Unsurprisingly default mode is HiLink, but luckily it can be changed to Stick mode getting rid at least one layer of NAT and related issues. Actually there's also third mode which is subset of Stick, instead of native NCM interface it uses legacy PPP over emulated serial port. This can be sometimes useful with older routers with USB port but you won't be able

Trying to upgrade Huawei E367u-2 from old 11.810.09.00.00 to latest available 11.838.01.00.1131 ends up with error code 16. This one was easy to fix - flash first  11.810.09.33.00 and then to latest.

Sierra Wireless 319U is fairly decent USB 3G dongle that supports up to 42Mbit/s DC-HSPA+. However it has nasty tendency to randomly hang .

All the hype with Windows 10 and still something as elementary as Windows Update keeps getting corrupted. Common failure appears to be it properly detecting required updates but then getting stuck at 0% when downloading them.
