Unrelated instability issues with Win7 on the D820 led me to a new PC, the Latitude E6500. My biggest issue was with a Windows Update driver that seemed to break A2DP, so I'd have to keep backing it out if I accidentally installed it. The same problems pretty much stuck around. Next was my upgrade to the full release of Windows 7 (32bit). Audio connectivity was finicky, especially after rebooting, but I could usually get it working again just by removing and re-pairing my headphones.
From here, I 'upgraded' to Windows 7 RC 32-bit, which worked OK with the Vista drivers for the D820. This was far from stable, but I could at least get it to work consistently by following a routine involving disabling and re-enabling the Bluetooth adapter and rebooting my headphones. To start out, a little background: My first success with A2DP was with my Dell D820 with WinXP and the Toshiba Bluetooth stack. I would say it's a hassle only on Windows 7, but in all honestly, my experiences with A2DP on WinXP weren't much better, just different. I thought I'd write up a little bit on my ongoing hassles with A2DP (Bluetooth Stereo Headphones) on Windows 7. Install Realtek Bluetooth A2dp Device driver for Windows 10 圆4, or download DriverPack Solution software for automatic driver installation and update.
