I have finally managed to get this working as follows:
1. /etc/modprobe.d/alsa-base.conf
a) comment out all references to # options snd-usb-audio index=-2
b) add lines at end of file
# Force Sennheiser PC 8
alias snd-card-3 snd-usb-audio
options snd-usb-audio index=3 vid=0x1395 pid=0x0025
2. Test by manually loading module `sudo modprobe snd-usb-audio` and
confirm 'aplayl -l' shows card and you can select and test it in sound
settings.
3. Organise to always load this module on boot by adding following line to
/etc/modules
snd-usb-audio
