Trying to get rear speakers to "work". 4.0 surround sound system
(Creative) was working fine in 15.04. Then stopped with upgrade to
15.10... :/
I have been looking for a couple months now for solution but nothing.
Tried forums, wikis, and even freenode ubuntu channels. Usually by now
I would have found a fix online or messed with and re-installed a lot of
stuff and figured it out/fixed it myself. Maybe I'm getting old. :D
haha
What would have changed in pulse or alsa or whatever so drastically from
15.04 to 15.10?
(apt-cache policy pulseaudio)
pulseaudio:
Installed: 1:6.0-0ubuntu13
Candidate: 1:6.0-0ubuntu13
