Solved?
Thanks for this forum Ubuntu. I'm a Fedora user, but I frequently find
solutions here
I have an XPS 9550 along with the issue of the headphone microphone not
working. I changed /etc/modprobe.d/alsa.conf from:
options snd-hda-intel single_cmd=1 probe_mask=1 model=dell-headset-multi
This is most likely not an issue with Ubuntu - I'm a Fedora user and I
have the same problem.
Many times hitting Send / Receive ends up with a dialog that never
returns, after which I restart Evolution and it gets fast again.
The problem *seems* to also happen when changing networks or resuming
