@Chris. I too have a Jabra GN9350e and I also get the weird mouse behavior. Not sure if it has anything to do with this bug at all.
A work-around I found so far is to make sure the base is set to 'PC' mode before you plug it to the USB port. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1002952 Title: [meta-bug] Invalid extra "Digital output S/PDIF" device for USB cards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1002952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
