Sound stops working randomly until application restart

Hi! I have Ryzen 3900, nVidia 2070S, Soundblaster Creative AE-5 Plus (DAMNED)
Manjaro 21 xfce x64.
NO SOUND!
Alsamixer, Pulseuadio, Qastools recognize the card periodically. Rebooting doesn’t help regularly, only from time to time. In this case, the sound may or may not appear. Kernels 5.12 / 5.13 / 5.14.
Help, please. Thanks.
