I just changed back to wireless mode to try this out and I also heard the buzz/clicking under certain conditions. My network is 802.11b, by the way. A few more interesting pieces of info, which may help you debug: 1) I used the volume controls to recreate the buzz/clicking (nothing playing). While I was turning the volume up and down, I noticed that the volume of the buzz/clicking does not change. That's probably not all that useful, now that I think about it; volume control is probably not at the headphone amp anyway, since it affects the speaker outputs as well. 2) The antenna orientation (or squeezebox orientation--not the same thing) both affect the level of noise (but read (3) and (4)!). Noise level is not always equal in each ear. Sometimes it goes from the one ear over to the other. Sometimes louder in one ear, etc. 3) I can *remove* the external antenna and still hear the noise. I discovered the next part accidentally. The SB2 had gone over to the RSS screensaver. (When the screensaver is scrolling a fairly constant level buzzing can be heard, which is useful for debugging.) When I started to put the SB2 back up on top of my (metal) CD player, I heard a fairly loud buzzing (left ear only). [Read on; it's not the CD player.] I started playing with the power cord and found that I could cause the noise level to increase when a section of the power cord was brought close to the opposite (right) side of the SB2. But I don't think it's coming from the power cord, because I can put the headphone cord and power cord close together, but away from the SB2 body and hear no noise. 4) Another accident: with the external antenna removed, I turned the SB2 so that the screen was facing me and the left side was toward the floor (top of the SB2 facing to my left). The noise increased. Then I saw that my headphone cord was crossing straight underneath the SB2 (the bottom side of the SB2 is to my right). I then raised the headphone cord so that it was no longer near the left side of the SB2. The noise decreased. The loudest buzzing occurs when I cross the headphone cord almost across the center of the bottom of the SB2, but slightly diagonally toward the front (any orientation of the SB2). Oh, and it flips from left ear to right ear and I have no idea what causes that. My stereo equipment was all powered off for these test, by the way. Only the SB2 was powered. - Dave -- Dave D _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
