Bad image. :\ http://stuge.se/tvtime-alt3.png > let me know if this works out it seems like a physical USB issue. Normally I have the device connected through a bus-powered 4-port 2.0 hub based on a Genesys Logic chipset, lsusb attached. If I connect the device to the root hub, the artefact disappears. What physical issue do you think causes this? Could it be a power problem? Whatever the cause it's strange that I only see the artefact when muting, and only when muting one particular channel. //Peter
