Every now and then, the sound card stops working. I took a look at the system messages when it stops working. I see these messages:\r\n\r\n`\r\n[ 3152.500000] retire_capture_urb: 5000 callbacks suppressed\r\n[ 3157.510000] retire_capture_urb: 5000 callbacks suppressed\r\n[ 3162.520000] retire_capture_urb: 5000 callbacks suppressed\r\n[ 3167.530000] retire_capture_urb: 5000 callbacks suppressed`\r\n\r\nThe sound card starts working only after power cycling/rebooting the Yun. This is also seen with the official Yun image from the arduino repo. This seems like a USB driver issue. Any thoughts on how to resolve this?"}}
