</div></div>I was thinking. What happens to interference if you connect your<br>
bleutooth dongle through a cable, placing it about 1,5 m away from the<br>

With a 15m usb extension I have found clear sound away from the clutter of the tower etal. Thank-you. Now I just need to figure how to configure my asoundrc directory, but that should be a new thread, I think. Many thanks to all, this list rules! Daryl </div></div><br></div></div>
