[PATCH v2] ALSA: usb-audio: Add delay quirk for USB Audio Device
From: 胡连勤
Date: Wed Jan 15 2025 - 04:37:36 EST
From: Lianqin Hu <hulianqin@xxxxxxxx>
Audio control requests that sets sampling frequency sometimes fail on
this card. Adding delay between control messages eliminates that problem.

usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: USB Audio Device
