I previously used 12.04 where I was able to use digital output
for my USB headset and it worked miles better than analog. Now I installed (fresh install, deleted previous ubuntu partitions) 14.04 on the same computer and can only select analog output
, where the volume control is comparably bad.
Edit:
I am using the default Volume Control for Ubuntu 14.04 (64-bit) and my Headset is the Plantronics GameCom 780.
The only (not obvious) difference between my old 12.04 install and my new 14.04 install is that I do not have a /boot
partition anymore on 14.04.
