Correction, the UA-25Ex doesn't work either.
The sound dies out after a few minutes being used.
When the sound dies out, dmesg prints:
[ 550.114621] urb status -32
[ 551.601237] urb status -32
[ 551.681206] urb status -32
[ 553.563336] urb status -32
[ 565.588044] urb status -32
[ 566.786965] urb status -32
[ 625.130221] cannot submit urb 0, error -28: not enough bandwidth
If there is any other info I can provide, let me know,
