Freshly paired BT headphones work fine (with the general win7 audio-quality bugs included).
But if I try to reconnect the headphones weeks later, although connection is successful, the audio-sink simply doesn't work at all: Windows claims that headphones are still disconnected though headphones clearly connected, and I can actually change their settings in the properties.
After twiddling with the setting for a long time, I sometimes manage to trigger something unknown, and the Windows' "Installing drivers" dialog comes up and tells me that the Windows installs the BT audio subsystem again. But the audio still doesn't work and "Sound" dialog's "Playback" tab still shows the headphones as "disconnected".
To make it work again, I have to delete the pairing, and re-pair again. (And repeat configuration of the headphones again - to minimize the usual Win7 BT audio glitches.)
Is there any way to avoid the hustle? Or BT audio is really truly broken on the Win7?
