I have exactly the same problem, but on a Fujitsu-Siemens AMILO Pro v2010: Garbled sound when an usb device is attached. But my audio card is a VIA VT823... AC97 (vendor 0x1106, device 0x3059) and the USB controller a VIA VT82... (vendor 0x1106, device 0x3104). If it help...
As soon as possible I will test it with kernel 2.6.17.9 or newest. bye Andrea -- Sound from ES1978 Maestro 2E garbled when USB CD-ROM drive plugged in https://launchpad.net/bugs/21057 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
