Intermittent USB soundcard error "usb_set_interface failed"
I have an external sound card that will play just fine for an undefined amount of time anywhere from a few seconds up to an hour or so. Then suddenly the output changes to a terrible buzzing sound and no music comes through. Amarok continues to play as if nothing has gone wrong until the device is unplugged and forces the switch to onboard sound.
I've also seen the usb_set_interface failed (-71) returned as well. I'm using a Dell Inspiron N5110 laptop running 12.10 with the latest updates. The sound card model number is SB1240. I have tested it on different usb ports and the same results appear using either the 3.0 or 2.0 ports. I will not have another system to test this on for a few days but I'm thinking that might be the next step. Is this a known/common issue? I haven't had much luck searching for usb_set_interface failed except for the source code that generates the error.
