Issues with Plantronics DA70 DAC/Headset - Querying sample rate

Hi guys, hope you can help advise on a strange issue I'm having with a Plantronics DA70 USB DAC, used as a headset.
Most times when I connect the USB DAC/headset, I receive the following errors in dmesg, and the application I'm trying to open (e.g Teams, Skype, GoToMeeting in Chrome) will hang:

[23597.580910] usb 2-1.2: 2:1: cannot set freq 44100 to ep 0x81

I have to unplug and reconnect the USB headset several times and maybe 1 attempt out of 10 will work successfully.

I think Plantronics manufacturer ID is already included in the mainline kernel's quirks.c file, but still having the issue. Currently running kernal 5.5.8-arch1-1.

Any advice on how to troubleshoot or pinpoint the issue would be much appreciated.

Thanks!
