Public bug reported: I re-installed Ubuntu, and I found that "line in" from the sound card wouldn't play. I use my PC for TV audio: TV audio out in PC sound card in, and it plays. But, like when I installed Ubuntu a couple of years ago, that doesn't work by default.
I started Alsamixer in a shell, but that doesn't have a control for "line in". The sound panel doesn't help either. As it turns out, found that on a forum, you need to install gnome-alsamixer. That does have a control for "Line" which you can unmute, and have sound. I think this is a bug. Alsamixer should have the same features as gnome- alsamixer, in Unity you shouldn't need a gnome feature. I have Ubuntu 15.04, with the latest updates. I have an MSI X99S Xpower AC motherboard with integrated intel audio. version:Ubuntu 3.19.0-30.33-generic 3.19.8-ckt6 ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502504 Title: Alsamixer doesn't show "Line in".
