So, I've started plugging my headphone into my monitor's headphone jack rather than the analog audio ports in my CPU and there's been a drastic reduction in the volume levels. The volume is often insufficient even when everything in my volume settings is maxed out. Here are a couple of things to try out in KDE/Kubuntu/Linux that might help alleviate the situation.
- In a terminal, run
alsamixer. In the ensuing interface, you might need to press F6 and go through each of the sound card options until you see a graphical equalizer much like the one you see when you click the sound option in your system tray. Max everything out here using your arrow keys.
- If that doesn't solve you problem, run
pavucontrol(or Pulse Audio Volume Control in K Menu). Look through the tabs and in particular, the Output Devices tab. In my case, I could see a port specific volume control here and maxing it fixed my problem.
The volume is still not as loud as it was via the audio jacks I was using earlier. But it's much better now.
Hope this helps :)
