Got the boxes bought by Bluetooth to listen to my music (MP3 collection on the notebook). The sound quality I found surprisingly good. 'm Not even sure if it is not as good as my old Yamaha system with CD, so with classic amplifiers and classic boxing. The boxes were there within two days and the link with the PC went in less than two minutes. However, the connection does not automatically restart after the notebook is in standby mode was, even if it is deposited in my Bluetooth settings (ie, automatic connection is enabled in the Bluetooth Manager). But as I discovered, is not due to the pits but the Bluetooth Manager. There, simply click again on "Connect" and then it goes back. Thank you still respect the responses of other customers. My question to the sound card.
