Thank you very much for the kind reply.
You made the dmesg warning go away, but that didn't necessarily solve the underlying issue. May I ask that you post the "lsusb -v -d 1397:0507" ?
Here it is, connected to a USB 2.0 port (xHCI still enabled).
Thanks, Nandakumar!
Have you tried unloading the snd-usb-audio module and the reloading it with implicit_fb=1 as in "modprobe -r snd-usb-audio" and "modprobe snd-usb-audio implicit_fb=1" ?
If not, try it. If it works and your playback issues are gone then your device may just need a quirk. If it doesn't work we still have dyndbg to go through.
Last but not least, please use a vanilla kernel for these tests.
Thank you, Geraldo Nascimento
