Hi alsa-devel team. This device from linux from 5.2 (my first plug) to now with 5.8.1, the only way to use it properly is to run linux after windows reboot. If linux is run at poweron, the device is correctly seen by the kernel but muted. Here the results of alsa-info.sh when card is working , not working, a diff, dmesg and lsusb -v https://paste.ee/p/YrJSP#pRmvQ58T7sCeulHr1ZSluw2cTQt7exsh Waiting to give more information, Best Regards.
