Description
Hi,
I have a 2.1 sound system.
When I use the profile "stereo" in pusle audio volume control (Xubuntu 15.04), the subwoofer outputs sound (but it is an incorrect track, sort of miwed with right channel)
When I use profile "Analog surround 2.1", I get no sound at all from subwoofer.
An historical bug was opened on launchpad. There's a lot of history and diffrent versions tested. Read from post #115 : https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1040873/comments/115
Some logs:
$ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version k3.19.0-25-generic.
