Public bug reported:
With this headset:
[ 9922.706941] usb 1-1.4: new full-speed USB device number 4 using ehci-pci
[ 9922.805274] usb 1-1.4: New USB device found, idVendor=1ea7, idProduct=0055
[ 9922.805279] usb 1-1.4: New USB device strings: Mfr=1, Product=2,
SerialNumber=0
[ 9922.805282] usb
When I do:
$ amixer -c1 cset iface=MIXER,name='Speaker Playback Volume',index=0 3

to parse module arguments
Feb 14 11:36:30 erz pulseaudio[3406]: [pulseaudio] module.c: Failed to load
module "module-udev-detect"
