Title:
[USB-Audio - Audioengine D3, playback] fails after a while (a second)
Status in linux package in Ubuntu:
Expired
Bug description:
USB DAC stops playing sound after a second.
I had problem with kernel 4.15.
So, I tried upgrading to 4.19 but still issue persists.
I think, we might need to add it to sound/usb/quirks.c
I see following in dmesg
[ 155.552404] usb 1-1.4.1: new full-speed USB device number 10 using xhci_hcd

And lsusb -v has following entry for the device.
