problem with Jabra EVOLVE 20 headset, and usb quirk update

[Hin-Tak Leung]

Hi,

This is a headset i.e. with both a ear set, and a microphone - the playback seems fine, but recording only accept one setting - and also I was having problem with zoom using it ("cannot get freq" see the tail end of this e-mail). switching via the gnome setting -> sound (from built-in hda) seems sluggish, and occasionally the volume is frozen to mute and unresponsive to unmute.

$ arecord -f S16_LE -D front:CARD=J20,DEV=0 -d 10 wonder.wav
Recording WAVE 'wonder.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono
Warning: rate is not accurate (requested = 8000Hz, got = 16000Hz)
         please, try the plug plugin 

and, also zoom seems to have problem getting at the microphone. I read that it is something to do with rate querying?

Attached is "lsusb -vvvv -d 0b0e:0301  > usb-audio-lsusb-vvvv-0b0e:0301".

I have tried just letting udev doing its thing, or preloading the module with with 
modprobe snd_usb_audio quirk_alias=0b0e0301:0b0e0349
or
modprobe snd_usb_audio quirk_alias=0b0e0301:0b0e030b
as below. But the "cannot get freq" message stays.

This is based on similar vendor ids - 

sound/usb/format.c:	if (chip->usb_id == USB_ID(0x0b0e, 0x030b)) {
sound/usb/quirks.c:	     chip->usb_id == USB_ID(0x0b0e, 0x0349) ||

The device does not seems to be under quirks.c:snd_usb_ctl_msg_quirk() ( I don't really get delays,  I think), 

format.c:formatparse_audio_format_rates_v1() seems to be somewhat related, but I don't have issue with playback, just capture.

Should I insert this vid/pid into bool snd_usb_get_sample_rate_quirk(struct snd_usb_audio *chip) as suggested elsewhere? I am just uncomfortable doing so as there isn't a quirk for this vendor there, yet. Also, related question: the format rate quirk routine and usb_ctl_msg_quirk routine does not seem to be affected by the alias_quirk list, as far as I understand and read the code?

Here is the dmesg, under plain udev autoprobe, and the two preloads. I hope this is enough info. Please feel free to ask for more.
(I also maintain https://github.com/HinTak/sound-usb-dkms/ as part of my previous job, but this device/usage is slightly complicated as I need to sign modified modules due to UEFI ; so I'd rather try something that has a chance of working, then just blindly try any modification)
