WM Bluetooth Volume. (Searched). I haven't quite found a thread for this at all. When using WM with bluetooth, either headset or dongle to computer, I can not change the volume. 0% is nothing at 5% it's as loud as it gets and anything over makes no difference. While using TCPMP I can change the volume as I would expect. Only thing is even with the Zero codec pack TCPMP complains about windows media files both video and audio. So I guess if I could find codecs that worked for TCPMP or a volume fix for WM I'd be thrilled. Thanks..
