I have lost sound on all of my clients connected to one server, Dell GX1 clients , had no trouble until I tried the update test to get rid of double floppy icons. V5. (LTSP 4.2.3) The other server that is running V5.0 without the floppy/usb LTSP 4.2.3 update is running sound. (Same clients Dell GX1) What changed in the update that I tested. Thanks Dave M
