MSI Z97 Gaming 5 + Kubuntu 14.10 = weird sound bug

[mhajii210]

Hi guys. I recently upgraded my PC. What's weird is when running Kubuntu I have to plug my stereo speakers into the SS-Out (subwoofer) jack to get sound working properly. If I plug it into the red Line Out jack at the rear (the one I'm supposed to use) the volume is WAY too low. Of course under Windows 8.1 64-bit I have to plug the speakers into the red Line Out jack. How would I go about correcting this bug I have all volumes maxed out and I have it set to use analog stereo duplex. I tried using hdjackrestack but I have no idea what I'm doing.

1 try opening a terminal (konsole) and enter

alsamixer

and see if all the channels are up .



use the right and left arrow keys to switch chanels the up and down arrows for volume and the M key to mute unmute and the escape key to exit.

2 install the package pavucontrol (pulse audio volume control)

sudo apt install pavucontrol

and try using it to setup the sound ,,,,,,it may take some trial and error

Thank you for the reply. I discovered that I have to shut down the pc after running Windows 8.1 instead of merely restarting it. If I power down completely and then boot into Kubuntu, the sound issue is fixed! I then have to plug the stereo speakers into the red Line Out jack and the volume issue is completely resolved. Weird that restarting from Windows and booting into Kubuntu somehow messes up the audio. Since I discovered an easy way to fix it, I'm not going to worry about it. I wonder why this happens though?

Great news! I discovered this https://bugs.launchpad.net/ubuntu/+s...x/+bug/1357723 and I followed the instructions here http://www.linux.com/community/blogs...mintpeppermint to update the kernel manually. It seems this bug is a known issue with older kernel builds (including the one that comes with Kubuntu 14.10 Plasma 4). Kernel 3.18 corrects my sound bug after a restart from Windows!! I'm a VERY happy camper.

you know now that you mention that ,,,,, I do remember 1 box I had (do not remember the specks ,,long time ago) that if I rebooted from XP I had no front output from the sound , but a shutdown and restart it worked .
